Summary Of Significant Accounting Policies [Abstract]	'
Summary Of Significant Accounting Policies	'
	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Presentation of Financial Statements
	The Company’s consolidated financial statements include 100% of the assets and liabilities of Nutrisystem, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
	Interim Financial Statements
	The Company’s consolidated financial statements as of and for the three months ended March 31, 2014 and 2013 are unaudited and, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the Company’s financial position and results of operations for these interim periods. Accordingly, readers of these consolidated financial statements should refer to the Company’s audited consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), and the related notes thereto, as of and for the year ended December 31, 2013, which are included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013 (the “2013 Annual Report”) as certain footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted from this report pursuant to the rules of the Securities and Exchange Commission (the “SEC”). The results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results to be expected for the year ending December 31, 2014.
	Cash Equivalents and Short Term Investments
	Cash equivalents include only securities having a maturity of three months or less at the time of purchase. At March 31, 2014 and December 31, 2013, demand accounts and money market accounts comprised all of the Company’s cash and cash equivalents.
	Short term investments consist of investments in government and agency securities and corporate debt securities with original maturities of greater than three months at the time of purchase. The Company classifies these investments as available-for-sale securities. These investments are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive income, a component of stockholders’ equity, net of related tax effects.
	At March 31, 2014, cash, cash equivalents and short term investments consisted of the following:
		Cost			Gross			Gross			Estimated
					Unrealized			Unrealized			Fair Value
					Gains			Losses
	Cash	$	12,783		$	0		$	0		$	12,783
	Money market account		144			0			0			144
	Government and agency securities		9,771			25			(7	)		9,789
	Corporate debt securities		6,771			31			(29	)		6,773
		$	29,469		$	56		$	(36	)	$	29,489
	At December 31, 2013, cash, cash equivalents and short term investments consisted of the following:
		Cost			Gross			Gross			Estimated
					Unrealized			Unrealized			Fair Value
					Gains			Losses
	Cash	$	9,660		$	0		$	0		$	9,660
	Money market account		112			0			0			112
	Government and agency securities		9,857			20			(10	)		9,867
	Corporate debt securities		6,682			35			(33	)		6,684
		$	26,311		$	55		$	(43	)	$	26,323
	Fixed Assets
	Fixed assets are stated at cost. Depreciation expense is calculated using the straight-line method over the estimated useful lives of the related assets, which are generally two to seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the related lease term. Expenditures for repairs and maintenance are charged to expense as incurred, while major renewals and improvements are capitalized.
	Included in fixed assets is the capitalized cost of internal-use software and website development incurred during the application development stage. Capitalized costs are amortized using the straight-line method over the estimated useful life of the asset, which is generally two to five years. Costs incurred related to planning or maintenance of internal-use software and website development are charged to expense as incurred. The net book value of capitalized software was $11,781 and $11,473 at March 31, 2014 and December 31, 2013, respectively.
	Revenue Recognition
	Revenue from direct to consumer product sales is recognized when the earnings process is complete, which is upon transfer of title to the product. Recognition of revenue upon shipment meets the revenue recognition criteria in that persuasive evidence of an arrangement exists, delivery has occurred, the selling price is fixed and determinable and collection is reasonably assured. The Company also sells prepaid program cards to wholesalers and retailers. Revenue from these cards is recognized after the card is redeemed online at the Company’s website or via telephone by the customer and the product is shipped to the customer. Revenue from the retail programs is recognized when the product is received at the seller’s location.
	Deferred revenue consists primarily of unredeemed prepaid gift cards and unshipped frozen foods. When a customer orders the frozen program, two separate shipments are delivered. The first shipment contains Nutrisystem’s standard shelf-stable food. The second shipment contains the frozen foods and is generally delivered within a week of a customer’s order. Both shipments qualify as separate units of accounting and the fair value is based on estimated selling prices of both units.
	Direct to consumer customers may return unopened shelf-stable products within 30 days of purchase in order to receive a refund or credit. Frozen products are non-returnable and non-refundable unless the order is canceled within 14 days of delivery. Estimated returns are accrued at the time the sale is recognized and actual returns are tracked monthly.
	The Company reviews the reserves for customer returns at each reporting period and adjusts them to reflect data available at that time. To estimate reserves for returns, the Company considers actual return rates in preceding periods and changes in product offerings or marketing methods that might impact returns going forward. To the extent the estimate of returns changes, the Company will adjust the reserve, which will impact the amount of revenue recognized in the period of the adjustment. The provision for estimated returns for the three months ended March 31, 2014 and 2013 was $3,909 and $3,845, respectively. The reserve for estimated returns incurred but not received and processed was $1,076 and $637 at March 31, 2014 and December 31, 2013, respectively, and has been included in other accrued expenses and current liabilities in the accompanying consolidated balance sheets.
	Revenue from product sales includes amounts billed for shipping and handling and is presented net of estimated returns and billed sales tax. Revenue from the retail programs is also net of any trade allowances, reclamation reserves or broker commissions. Revenue from shipping and handling charges were $605 and $641 for the three months ended March 31, 2014 and 2013, respectively. Shipping-related costs are included in cost of revenue in the accompanying consolidated statements of operations.
	Dependence on Suppliers
	Approximately 14% and 11% of inventory purchases for the three months ended March 31, 2014 were from two suppliers. The Company has supply arrangements with these suppliers that require the Company to make minimum purchases. For the three months ended March 31, 2013, these suppliers supplied approximately 13% and 9% of inventory purchases. Additionally, a third supplier during the three months ended March 31, 2013 supplied approximately 10% of inventory purchases.
	The Company outsources 100% of its fulfillment operations to a third-party provider and more than 90% of its orders are shipped by one third party provider.
	Vendor Rebates
	One of the Company’s suppliers provides for rebates based on purchasing levels. The Company accounts for this rebate on an accrual basis as purchases are made at a rebate percentage determined based upon the estimated total purchases from the vendor. The estimated rebate is recorded as a receivable from the vendor with a corresponding reduction in the carrying value of purchased inventory, and is reflected in the consolidated statements of operations when the associated inventory is sold. The rebate period is June 1 through May 31 of each year. For the three months ended March 31, 2014 and 2013, the Company reduced cost of revenue by $276 and $358, respectively, for these rebates. A receivable of $446 and $182 at March 31, 2014 and December 31, 2013, respectively, has been recorded in receivables in the accompanying consolidated balance sheets. Historically, the actual rebate received from the vendor has closely matched the estimated rebate recorded. An adjustment is made to the estimate upon determination of the final rebate.
	Fair Value of Financial Instruments
	A three-tier fair value hierarchy has been established by the Financial Accounting Standards Board (“FASB”) to prioritize the inputs used in measuring fair value. These tiers are as follows:
	Level 1—Valuations based on quoted prices for identical assets and liabilities in active markets.
	Level 2—Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.
	Level 3—Valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.
	The fair values of the Company’s Level 1 instruments are based on quoted prices in active exchange markets for identical assets. The Company had no Level 2 or 3 instruments at March 31, 2014 and December 31, 2013.
	The following table summarizes the Company’s financial assets measured at fair value at March 31, 2014:
		Total Fair Value			Quoted Prices in Active
					Markets for Identical
					Assets (Level 1)
	Money market account	$	144		$	144
	Government and agency securities		9,789			9,789
	Corporate debt securities		6,773			6,773
	Total assets	$	16,706		$	16,706
	The following table summarizes the Company’s financial assets measured at fair value at December 31, 2013:
		Total Fair Value			Quoted Prices in Active
					Markets for Identical
					Assets (Level 1)
	Money market account	$	112		$	112
	Government and agency securities		9,867			9,867
	Corporate debt securities		6,684			6,684
	Total assets	$	16,663		$	16,663
	Earnings Per Share
The Company uses the two-class method to calculate earnings per share (“EPS”) as the unvested restricted stock issued under the Company’s equity incentive plans are participating shares with nonforfeitable rights to dividends. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the number of weighted average shares outstanding during the period. Undistributed losses are not allocated to unvested restricted stock as the restricted stockholders are not obligated to share in the losses. The following table sets forth the computation of basic and diluted EPS:
	Three Months Ended
	March 31,
	2014			2013
Net income (loss)	$	224		$	(640	)
Net income allocated to unvested restricted stock		(1	)		0
Net income (loss) allocated to common shares	$	223		$	(640	)
Weighted average shares outstanding:
Basic		28,065			27,759
Effect of dilutive securities		424			0
Diluted		28,489			27,759
Basic income (loss) per common share	$	0.01		$	(0.02	)
Diluted income (loss) per common share	$	0.01		$	(0.02	)
In the three months ended March 31, 2014 and 2013, common stock equivalents representing 355 and 1,768 shares of common stock, respectively, were excluded from weighted average shares outstanding for diluted income per common share purposes because the effect would be anti-dilutive. In the three months ended March 31, 2013, diluted loss per common share was identical to basic loss per common share as the Company was in a net loss position and the impact of including common stock equivalents would be anti-dilutive.
Cash Flow Information
The Company made payments for income taxes of $18 in the three months ended March 31, 2014. In the three months ended March 31, 2013, the Company made no payments for income taxes. Interest payments in the three months ended March 31, 2014 and 2013 were $59 and $40, respectively. For the three months ended March 31, 2014 and 2013, the Company had non-cash capital additions of $35 and $586, respectively, of unpaid invoices in accounts payable and accrued expenses.
Recently Issued Accounting Pronouncements
In July 2013, the FASB issued Accounting Standards Update (“ASU”) 2013-11 which provides that an unrecognized tax benefit, or portion of an unrecognized tax benefit, would be presented in the financial statements as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward rather than a liability when the unrecognized tax benefit would reduce the net operating loss or other carryforward under the tax law of the applicable jurisdiction and the Company intends to use the deferred tax asset for this purpose. If an applicable deferred tax asset is not available or the tax law does not require the company to use, and the company does not expect to use, the applicable deferred tax asset for such purpose, then the unrecognized tax benefit would be presented as a liability in the financial statements and would not be combined with an unrelated deferred tax asset. ASU 2013-11 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2013. The ASU should be applied prospectively to all unrecognized tax benefits that exist at the effective date; however, retrospective application is permitted. Effective January 1, 2014, the Company adopted ASU 2013-11 and reduced its deferred tax asset by the unrecognized tax benefit. The prior year consolidated balance sheet was reclassified to conform to the current year presentation.
Use of Estimates
The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and operating expenses during the reporting period. Actual results could differ from these estimates.

Credit Facility [Abstract]	'
Credit Facility	'
	3. CREDIT FACILITY
	On November 8, 2012, the Company entered into a $40,000 secured revolving credit facility, as amended (the “Credit Facility”), with a lender. The Credit Facility can be drawn upon through November 8, 2015, at which time all amounts must be repaid. There were no borrowings outstanding at March 31, 2014 or December 31, 2013.
	The Credit Facility provides for interest at either a base rate or a LIBOR rate, in each case plus an applicable margin. The base rate will be the highest of (i) the Administrative Agent’s prime rate, (ii) 0.50% percent above the Federal Funds Rate and (iii) the LIBOR rate for deposits in dollars for a one-month interest period as determined three business days prior to such date, plus 1.50%. The LIBOR rate is equal to the London Inter-Bank Offered Rate for the relevant term. The applicable margin is subject to adjustment based on the Company’s consolidated fixed charge coverage ratio and ranges from 0.25-1.25% per year for base rate loans and from 1.75-2.75% per year for LIBOR rate loans. The Company will also pay an unused line fee. The unused line fee is subject to adjustment based on the Company’s consolidated fixed charge coverage ratio and ranges from 0.25-0.375% per year. During the three months ended March 31, 2014 and 2013, the Company incurred no interest and $33 and $40 in an unused line fee, respectively. Interest payments and unused line fees are classified within interest expense, net in the accompanying consolidated statements of operations.
	The Credit Facility contains financial and other covenants including a minimum consolidated fixed charge coverage ratio, a minimum consolidated tangible net worth and a minimum consolidated liquidity ratio, and includes limitations on, among other things, capital expenditures, additional indebtedness, acquisitions, stock repurchases and restrictions on paying dividends in certain circumstances. As of March 31, 2014, the Company was in compliance with all covenants contained in the Credit Facility. Any obligations under the Credit Facility, as well as certain banking services and hedging obligations, are secured by substantially all of the assets of the Company and certain subsidiaries.
	At March 31, 2014, the Company had $111 of unamortized debt issuance costs associated with the Credit Facility that are being amortized over the remaining term of the Credit Facility.

	The Company issued 8 and 1 shares of common stock upon the exercise of stock options in the three months ended March 31, 2014 and 2013, respectively. During the three months ended March 31, 2014 and 2013, employees surrendered to the Company 41 and 40 shares of common stock, respectively, valued at $616 and $339, respectively, in satisfaction of minimum tax withholding obligations associated with the vesting of equity awards. These shares are included in treasury stock. No new shares of common stock were issued to board members or third-party marketing vendors during either the three months ended March 31, 2014 or 2013. Costs recognized for common stock previously issued to board members and third-party marketing vendors as compensation were $195 for the three months ended March 31, 2013. No amounts were recognized during the three months ended March 31, 2014. During both the three months ended March 31, 2014 and 2013, the Company paid a dividend of $0.175 per share to all stockholders of record.
	Preferred Stock
	The Company has authorized 5,000 shares of preferred stock issuable in series upon resolution of the Board of Directors. Unless otherwise required by law, the Board of Directors can, without stockholder approval, issue preferred stock in the future with voting and conversion rights that could adversely affect the voting power of the common stock. The issuance of preferred stock may have the effect of delaying, averting or preventing a change in control of the Company.

	Expected to vest at March 31, 2014		908		$	9.99		5.98	$	4,611
	The Company recorded compensation expense of $75 and $146 in the accompanying consolidated statements of operations during the three months ended March 31, 2014 and 2013, respectively, for stock option awards. The total intrinsic value of stock options exercised during the three months ended March 31, 2014 and 2013 was $27 and $4, respectively.
	The Company has issued restricted stock to employees generally with vesting terms ranging from two to five years. The fair value is equal to the market price of the Company’s common stock on the date of grant. Expense for restricted stock is amortized ratably over the vesting period. The following table summarizes the restricted stock activity for the three months ended March 31, 2014:
		Number of			Weighted-		Aggregate
		Shares			Average		Intrinsic Value
					Grant-Date
					Fair Value
	Nonvested, January 1, 2014		686		$	12.17
	Granted		113			14.94
	Vested		(141	)		11.87
	Forfeited		(35	)		12.77
	Nonvested, March 31, 2014		623		$	12.71	$	9,395
	Additionally, the Company grants performance-based and market-based restricted stock units. The performance-based units have performance conditions and service-based vesting conditions. Each vesting tranche is treated as an individual award and the compensation expense is recognized on a straight-line basis over the requisite service period for each tranche. The requisite service period is a combination of the performance period and the subsequent vesting period based on continued service. The level of achievement of such goals may cause the actual amount of units that ultimately vest to range from 0% to 150% of the original units granted. The Company recognizes expense ratably over the vesting period for performance-based restricted stock units when it is probable that the performance criteria specified will be achieved. The fair value is equal to the market price of the Company’s common stock on the date of grant.
	In 2012, grants of restricted stock units contained market-based conditions. Market-based awards entitle employees to vest in a number of units determined by the Company’s stock price return as compared to a set of comparator companies over a period, and will range from 0% to 200% of the original units granted. The fair value is calculated using a Monte Carlo simulation model on the date of grant. Compensation expense is recognized over the derived service periods using the straight-line method regardless of the outcome of the market conditions, so long as the award holder remains an employee through the requisite service period. These awards contained different measurement periods.
	The following table summarizes the restricted stock unit activity for the three months ended March 31, 2014:
		Number of			Weighted-		Aggregate
		Restricted			Average		Intrinsic Value
		Stock Units			Grant-Date

	Forfeited		(7	)		9.7
	Nonvested, March 31, 2014		293		$	10.2	$	4,422
	The Company recorded compensation of $1,018 and $1,161 in the accompanying consolidated statements of operations for the three months ended March 31, 2014 and 2013, respectively, in connection with the issuance of the restricted stock and restricted stock units. As of March 31, 2014, 597 shares of restricted stock and 285 restricted stock units were expected to vest.
	As of March 31, 2014, there was $9,720 of total unrecognized compensation expense related to unvested share-based compensation arrangements, including market-based units, which is expected to be recognized over a weighted-average period of 1.3 years. The total unrecognized compensation expense will be fully expensed through the first quarter of 2018.

	The Company is involved in various claims and routine litigation matters. In the opinion of management, after consultation with legal counsel, the outcomes of such matters are not anticipated to have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows in future years.
	Contractual Commitments
	The Company has entered into supply agreements with various food vendors. Several of these agreements provide for annual pricing, annual purchase obligations, as well as exclusivity in the production of certain products, with terms of five years or less. One agreement also provides rebates if certain volume thresholds are exceeded. The Company anticipates it will meet all annual purchase obligations in 2014.

Income Taxes	'
	7. INCOME TAXES
	The Company recorded income taxes at an estimated effective income tax rate applied to income (loss) before income taxes of 34.5% and 43.8% in the three months ended March 31, 2014 and 2013, respectively. The Company offsets taxable income for state tax purposes with net operating loss carryforwards. At December 31, 2013, the Company had net operating loss carryforwards of approximately $29,684 for state tax purposes. For state tax purposes, there is a limitation on the amount of net operating loss carryforwards that can be utilized in a given year to offset state taxable income and management believes that some of the net operating loss carryforwards will be subject to this annual limit in 2014. State net operating loss carryforwards will begin to expire in 2025. The total amount of gross unrecognized tax benefits as of March 31, 2014 and December 31, 2013 was $346 and $311, respectively. The total amount of unrecognized tax benefits that, if recognized, would affect the effective income tax rate is approximately $225 and $202 as of March 31, 2014 and December 31, 2013, respectively.
	In 2013, the Company recorded a valuation allowance of $800 against its deferred tax asset generated for charitable contributions. The Company recorded the valuation allowance to reduce the deferred tax asset to an amount it expects is more likely than not to be realized due to the short carryforward period for this temporary difference. Based on the projected level of future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the remaining net deferred tax assets.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2014
Summary Of Significant Accounting Policies [Abstract]	'
Presentation of Financial Statements, Policy	'
	Presentation of Financial Statements
	The Company’s consolidated financial statements include 100% of the assets and liabilities of Nutrisystem, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
Interim Financial Statements, Policy	'
	Interim Financial Statements
	The Company’s consolidated financial statements as of and for the three months ended March 31, 2014 and 2013 are unaudited and, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the Company’s financial position and results of operations for these interim periods. Accordingly, readers of these consolidated financial statements should refer to the Company’s audited consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), and the related notes thereto, as of and for the year ended December 31, 2013, which are included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013 (the “2013 Annual Report”) as certain footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted from this report pursuant to the rules of the Securities and Exchange Commission (the “SEC”). The results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results to be expected for the year ending December 31, 2014.
Cash Equivalents and Short Term Investments, Policy	'
	Cash Equivalents and Short Term Investments
	Cash equivalents include only securities having a maturity of three months or less at the time of purchase. At March 31, 2014 and December 31, 2013, demand accounts and money market accounts comprised all of the Company’s cash and cash equivalents.
	Short term investments consist of investments in government and agency securities and corporate debt securities with original maturities of greater than three months at the time of purchase. The Company classifies these investments as available-for-sale securities. These investments are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive income, a component of stockholders’ equity, net of related tax effects.
	At March 31, 2014, cash, cash equivalents and short term investments consisted of the following:
		Cost			Gross			Gross			Estimated
					Unrealized			Unrealized			Fair Value
					Gains			Losses
	Cash	$	12,783		$	0		$	0		$	12,783
	Money market account		144			0			0			144

	Corporate debt securities		6,682			35			(33	)		6,684
		$	26,311		$	55		$	(43	)	$	26,323
Fixed Assets, Policy	'
	Fixed Assets
	Fixed assets are stated at cost. Depreciation expense is calculated using the straight-line method over the estimated useful lives of the related assets, which are generally two to seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the related lease term. Expenditures for repairs and maintenance are charged to expense as incurred, while major renewals and improvements are capitalized.
	Included in fixed assets is the capitalized cost of internal-use software and website development incurred during the application development stage. Capitalized costs are amortized using the straight-line method over the estimated useful life of the asset, which is generally two to five years. Costs incurred related to planning or maintenance of internal-use software and website development are charged to expense as incurred. The net book value of capitalized software was $11,781 and $11,473 at March 31, 2014 and December 31, 2013, respectively.
Revenue Recognition, Policy	'
	Revenue Recognition
	Revenue from direct to consumer product sales is recognized when the earnings process is complete, which is upon transfer of title to the product. Recognition of revenue upon shipment meets the revenue recognition criteria in that persuasive evidence of an arrangement exists, delivery has occurred, the selling price is fixed and determinable and collection is reasonably assured. The Company also sells prepaid program cards to wholesalers and retailers. Revenue from these cards is recognized after the card is redeemed online at the Company’s website or via telephone by the customer and the product is shipped to the customer. Revenue from the retail programs is recognized when the product is received at the seller’s location.
	Deferred revenue consists primarily of unredeemed prepaid gift cards and unshipped frozen foods. When a customer orders the frozen program, two separate shipments are delivered. The first shipment contains Nutrisystem’s standard shelf-stable food. The second shipment contains the frozen foods and is generally delivered within a week of a customer’s order. Both shipments qualify as separate units of accounting and the fair value is based on estimated selling prices of both units.
	Direct to consumer customers may return unopened shelf-stable products within 30 days of purchase in order to receive a refund or credit. Frozen products are non-returnable and non-refundable unless the order is canceled within 14 days of delivery. Estimated returns are accrued at the time the sale is recognized and actual returns are tracked monthly.
	The Company reviews the reserves for customer returns at each reporting period and adjusts them to reflect data available at that time. To estimate reserves for returns, the Company considers actual return rates in preceding periods and changes in product offerings or marketing methods that might impact returns going forward. To the extent the estimate of returns changes, the Company will adjust the reserve, which will impact the amount of revenue recognized in the period of the adjustment. The provision for estimated returns for the three months ended March 31, 2014 and 2013 was $3,909 and $3,845, respectively. The reserve for estimated returns incurred but not received and processed was $1,076 and $637 at March 31, 2014 and December 31, 2013, respectively, and has been included in other accrued expenses and current liabilities in the accompanying consolidated balance sheets.
	Revenue from product sales includes amounts billed for shipping and handling and is presented net of estimated returns and billed sales tax. Revenue from the retail programs is also net of any trade allowances, reclamation reserves or broker commissions. Revenue from shipping and handling charges were $605 and $641 for the three months ended March 31, 2014 and 2013, respectively. Shipping-related costs are included in cost of revenue in the accompanying consolidated statements of operations.
Dependence on Suppliers, Policy	'
	Dependence on Suppliers
	Approximately 14% and 11% of inventory purchases for the three months ended March 31, 2014 were from two suppliers. The Company has supply arrangements with these suppliers that require the Company to make minimum purchases. For the three months ended March 31, 2013, these suppliers supplied approximately 13% and 9% of inventory purchases. Additionally, a third supplier during the three months ended March 31, 2013 supplied approximately 10% of inventory purchases.
	The Company outsources 100% of its fulfillment operations to a third-party provider and more than 90% of its orders are shipped by one third party provider.
Vendor Rebates, Policy	'
	Vendor Rebates
	One of the Company’s suppliers provides for rebates based on purchasing levels. The Company accounts for this rebate on an accrual basis as purchases are made at a rebate percentage determined based upon the estimated total purchases from the vendor. The estimated rebate is recorded as a receivable from the vendor with a corresponding reduction in the carrying value of purchased inventory, and is reflected in the consolidated statements of operations when the associated inventory is sold. The rebate period is June 1 through May 31 of each year. For the three months ended March 31, 2014 and 2013, the Company reduced cost of revenue by $276 and $358, respectively, for these rebates. A receivable of $446 and $182 at March 31, 2014 and December 31, 2013, respectively, has been recorded in receivables in the accompanying consolidated balance sheets. Historically, the actual rebate received from the vendor has closely matched the estimated rebate recorded. An adjustment is made to the estimate upon determination of the final rebate.
Fair Value of Financial Instruments, Policy	'
	Fair Value of Financial Instruments
	A three-tier fair value hierarchy has been established by the Financial Accounting Standards Board (“FASB”) to prioritize the inputs used in measuring fair value. These tiers are as follows:
	Level 1—Valuations based on quoted prices for identical assets and liabilities in active markets.
	Level 2—Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.
	Level 3—Valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.
	The fair values of the Company’s Level 1 instruments are based on quoted prices in active exchange markets for identical assets. The Company had no Level 2 or 3 instruments at March 31, 2014 and December 31, 2013.
	The following table summarizes the Company’s financial assets measured at fair value at March 31, 2014:
		Total Fair Value			Quoted Prices in Active
					Markets for Identical
					Assets (Level 1)
	Money market account	$	144		$	144
	Government and agency securities		9,789			9,789
	Corporate debt securities		6,773			6,773
	Total assets	$	16,706		$	16,706
	The following table summarizes the Company’s financial assets measured at fair value at December 31, 2013:

	Money market account	$	112		$	112
	Government and agency securities		9,867			9,867
	Corporate debt securities		6,684			6,684
	Total assets	$	16,663		$	16,663
Earnings Per Share, Policy	'
	Earnings Per Share
	The Company uses the two-class method to calculate earnings per share (“EPS”) as the unvested restricted stock issued under the Company’s equity incentive plans are participating shares with nonforfeitable rights to dividends. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the number of weighted average shares outstanding during the period. Undistributed losses are not allocated to unvested restricted stock as the restricted stockholders are not obligated to share in the losses. The following table sets forth the computation of basic and diluted EPS:
		Three Months Ended
		March 31,
		2014			2013
	Net income (loss)	$	224		$	(640	)
	Net income allocated to unvested restricted stock		(1	)		0
	Net income (loss) allocated to common shares	$	223		$	(640	)
	Weighted average shares outstanding:
	Basic		28,065			27,759
	Effect of dilutive securities		424			0
	Diluted		28,489			27,759
	Basic income (loss) per common share	$	0.01		$	(0.02	)
	Diluted income (loss) per common share	$	0.01		$	(0.02	)
	In the three months ended March 31, 2014 and 2013, common stock equivalents representing 355 and 1,768 shares of common stock, respectively, were excluded from weighted average shares outstanding for diluted income per common share purposes because the effect would be anti-dilutive. In the three months ended March 31, 2013, diluted loss per common share was identical to basic loss per common share as the Company was in a net loss position and the impact of including common stock equivalents would be anti-dilutive.
Recently Issued Accounting Pronouncements, Policy	'
	Recently Issued Accounting Pronouncements
	In July 2013, the FASB issued Accounting Standards Update (“ASU”) 2013-11 which provides that an unrecognized tax benefit, or portion of an unrecognized tax benefit, would be presented in the financial statements as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward rather than a liability when the unrecognized tax benefit would reduce the net operating loss or other carryforward under the tax law of the applicable jurisdiction and the Company intends to use the deferred tax asset for this purpose. If an applicable deferred tax asset is not available or the tax law does not require the company to use, and the company does not expect to use, the applicable deferred tax asset for such purpose, then the unrecognized tax benefit would be presented as a liability in the financial statements and would not be combined with an unrelated deferred tax asset. ASU 2013-11 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2013. The ASU should be applied prospectively to all unrecognized tax benefits that exist at the effective date; however, retrospective application is permitted. Effective January 1, 2014, the Company adopted ASU 2013-11 and reduced its deferred tax asset by the unrecognized tax benefit. The prior year consolidated balance sheet was reclassified to conform to the current year presentation.
Use of Estimates, Policy	'
	Use of Estimates
	The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and operating expenses during the reporting period. Actual results could differ from these estimates.
