	Basis of Presentation and Principles of Consolidation
	The accompanying unaudited condensed consolidated balance sheet as of June 30, 2014, the unaudited condensed consolidated statements of operations and comprehensive income for the three and six months ended June 30, 2014 and 2013, and the unaudited condensed consolidated statements of cash flows for the six months ended June 30, 2014 and 2013 have been prepared on the same basis as the Company's audited consolidated financial statements and include all adjustments necessary for the fair presentation of its consolidated results of operations, financial position, comprehensive income and cash flows. Results for the interim periods are not necessarily indicative of results to be expected for the full year or any other future periods. The condensed consolidated balance sheet as of December 31, 2013 has been derived from the Company's audited financial statements, which are included in its 2013 Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 3, 2014.
	The significant accounting policies and certain financial information that are normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP"), but which are not required for interim reporting purposes, have been omitted. The unaudited condensed consolidated interim financial statements should be read in conjunction with the Company's audited consolidated financial statements for the year ended December 31, 2013.
	On May 21, 2014, the Board of Directors declared a two-for-one stock split of the Company’s outstanding common stock to be effected through a stock dividend. The additional shares were distributed on June 26, 2014 to shareholders of record at the close of business on June 9, 2014.  All references made to share or per share amounts in the accompanying consolidated financial statements and applicable disclosures reflect this two-for-one stock split.
	Concentration of Credit Risks
	Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash investments, accounts receivable and other receivables. The Company places its cash and cash equivalents in short-term instruments with high quality financial institutions and limits the amount of credit exposure in any one financial instrument.
	The Company periodically evaluates the collectability of amounts due from vendors for promotional and other incentives with reserves maintained for potential credit losses after consideration given to rights of offset against vendor payments.
	A credit review is completed for new customers and ongoing credit evaluations are performed periodically of existing customers, with reserves maintained for potential credit losses. Credit limits given to customers are based on a risk assessment of their ability to pay and other factors. Accounts receivable are typically not collateralized, but the Company may require prepayments or other guarantees whenever deemed necessary.
	Alimentation Couche-Tard, Inc. (“Couche-Tard”), the Company's largest customer, accounted for approximately 14.6% of the Company's total net sales for the three and six months ended June 30, 2014, and approximately 13.0% of the Company's total net sales for each of the same periods in 2013. No single customer accounted for 10% or more of the Company's accounts receivables as of June 30, 2014 or December 31, 2013.
	Recent Accounting Pronouncements
	On July 18, 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which requires an entity to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss ("NOL") carryforward, or similar tax loss or tax credit carryforward, rather than as a liability when (1) the uncertain tax position would reduce the NOL or other carryforward under the tax law of the applicable jurisdiction and (2) the entity intends to use the deferred tax asset for that purpose. This accounting standard update was adopted by the Company in the first quarter of 2014 and applied prospectively. There was no impact to our consolidated financial statements due to the adoption of this guidance.
	On May 28, 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. This standard is effective for the Company beginning in 2017 and allows for either full retrospective adoption or modified retrospective adoption with cumulative effect recognized at the date of initial adoption. Early adoption of this standard is not allowed. The Company is currently evaluating the impact of the adoption of ASU 2014-09 on its financial statements.
	In June 2014, the FASB issued Accounting Standards Update 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period: Topic 718 (ASU 2014-12). The standard states that a performance target in a share-based payment that affects vesting and that could be achieved after the requisite service period should be accounted for as a performance condition. This standard is effective for the Company beginning in 2016 and early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2014-12 on its financial statements.

	Inventories
	Inventories consist of the following (in millions):
		June 30,			December 31,
		2014			2013
	Inventories at FIFO, net of reserves	$	412.2		$	488.2
	Less: LIFO reserve	(106.1		)	(99.0		)
	Total inventories at LIFO, net of reserves	$	306.1		$	389.2
	Cost of goods sold reflects the application of the last-in, first-out (“LIFO”) method of valuing inventories in the U.S. based upon estimated annual producer price indices. Inventories in Canada are valued on a first-in, first-out (“FIFO”) basis, as LIFO is not a permitted inventory valuation method in Canada. During periods of rising prices, the LIFO method of costing inventories generally results in higher current costs being charged against income while lower costs are retained in inventories. Conversely, during periods of decreasing prices, the LIFO method of costing inventories generally results in lower current costs being charged against income and higher stated inventories. The Company recorded LIFO expense of $4.3 million and $3.7 million for the three months ended June 30, 2014 and 2013, respectively, and $7.1 million and $6.6 million for the six months ended June 30, 2014 and 2013, respectively.

	Amounts borrowed (Credit Facility)	$	5	$	46.3
	Obligations under capital leases	13		11.3
	Total long-term debt	$	18	$	57.6
	The Company has a revolving credit facility (“Credit Facility”) with a capacity of $200 million, which can be increased up to an additional $100 million, subject to certain provisions. All obligations under the Credit Facility are secured by first priority liens on substantially all of the Company’s present and future assets. The terms of the Credit Facility permit prepayment without penalty at any time (subject to customary breakage costs with respect to LIBOR or CDOR based loans prepaid prior to the end of an interest period). The margin added to the LIBOR or CDOR rate is currently a range of 125 to 175 basis points. In addition, the Credit Facility provides for stock repurchases of up to an aggregate of $50 million, not to exceed $15 million in any year, with a $75 million ceiling for dividends allowable over the term of the Credit Facility, which expires in May 2018.
	The Credit Facility contains restrictive covenants, including, among others: limitations on dividends and other restricted payments, other indebtedness, liens, investments and acquisitions and certain asset sales. As of June 30, 2014, the Company was in compliance with all of the covenants under the Credit Facility.
	Amounts borrowed, outstanding letters of credit and amounts available to borrow, net of certain reserves required under the Credit Facility, were as follows (in millions):
		June 30,		December 31,

	Average borrowings during the three and six months ended June 30, 2014 were $6.9 million and $10.2 million, respectively, with amounts borrowed, at any one time outstanding, ranging from zero to $46.3 million. For the three and six months ended June 30, 2013, average borrowings were $41.4 million and $37.9 million, respectively, with amounts borrowed, at any one time outstanding, ranging from zero to $112.0 million.
	The weighted-average interest rate on the revolving credit facility for the three and six months ended June 30, 2014 was 1.7% and 1.6%, respectively, compared to 1.9% and 2.0% for the same periods in 2013. The weighted-average interest rate is calculated based on the daily cost of borrowing, reflecting a blend of prime and LIBOR rates. The Company paid fees for unused facility and letter of credit participation, which are included in interest expense, of $0.2 million and $0.4 million during the three and six months ended June 30, 2014, respectively, and $0.2 million and $0.5 million during the three and six months ended June 30, 2013, respectively. The Company recorded charges related to amortization of debt issuance costs, which are included in interest expense, of $0.1 million and $0.2 million during the three and six months ended June 30, 2014 and 2013, respectively. Unamortized debt issuance costs were $1.3 million as of June 30, 2014 and $1.4 million as of December 31, 2013.

	Contingencies
	Litigation
	The Company and its insurers are plaintiffs in a lawsuit against Sonitrol Corporation. The case arose from the December 21, 2002 arson fire at the Denver warehouse, in which Sonitrol failed to detect and respond to a four-hour burglary and subsequent arson. In 2010, a jury found in favor of the Company and its insurers. Sonitrol appealed the judgment to the Colorado Appellate Court and on July 19, 2012, the Appellate Court upheld the trial court's ruling on two of the three issues being appealed but set aside the judgment and remanded the case back to the District Court for trial on the sole issue of damages. On April 29, 2013, the Colorado Supreme Court denied Sonitrol’s appeal and the case was returned to the District Court to resolve the sole issue of damages. On April 11, 2014, the damages trial concluded with a jury award of $2.75 million in favor of the Company and its insurers, finding that Sonitrol was liable for damages related only to the burglary and not the subsequent arson. The Company and its insurers are planning to appeal the jury’s findings. The Company is unable to predict when this litigation will be resolved and its ultimate outcome. Any monetary recovery from this lawsuit will be recognized only if and when it is finally paid to the Company.
	The Company is subject to certain legal proceedings, claims, investigations and administrative proceedings in the ordinary course of its business. The Company records a provision for a liability when it is both probable that the liability has been incurred and the amount of the liability can be reasonably estimated. These provisions, if any, are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. In the opinion of management, the outcome of pending litigation is not expected to have a material adverse effect on our results of operations or financial condition.

	The total gross amount of unrecognized tax benefits related to federal, state and foreign taxes was approximately $0.6 million at June 30, 2014 and December 31, 2013, all of which would impact the Company's effective tax rate, if recognized. The expiration of the statute of limitations for certain tax positions in future years and expected settlement of certain tax audit issues could impact the total gross amount of unrecognized tax benefits by $0.2 million through June 30, 2015.
	The Company files U.S. federal, state and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2010 to 2013 tax years remain subject to examination by federal and state tax authorities with the 2009 tax year still open for certain state tax authorities. The 2006 to 2013 tax years remain subject to examination by the tax authorities in Canada.

	In February 2014, the Company granted 138,800 performance-based shares to certain of its employees at a weighted-average grant date fair value of $36.79. The performance shares of 138,800 represent the maximum that can be earned.

Concentration of Credit Risk	'
	Concentration of Credit Risks
	Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash investments, accounts receivable and other receivables. The Company places its cash and cash equivalents in short-term instruments with high quality financial institutions and limits the amount of credit exposure in any one financial instrument.
	The Company periodically evaluates the collectability of amounts due from vendors for promotional and other incentives with reserves maintained for potential credit losses after consideration given to rights of offset against vendor payments.
	A credit review is completed for new customers and ongoing credit evaluations are performed periodically of existing customers, with reserves maintained for potential credit losses. Credit limits given to customers are based on a risk assessment of their ability to pay and other factors. Accounts receivable are typically not collateralized, but the Company may require prepayments or other guarantees whenever deemed necessary.

	Recent Accounting Pronouncements
	On July 18, 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which requires an entity to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss ("NOL") carryforward, or similar tax loss or tax credit carryforward, rather than as a liability when (1) the uncertain tax position would reduce the NOL or other carryforward under the tax law of the applicable jurisdiction and (2) the entity intends to use the deferred tax asset for that purpose. This accounting standard update was adopted by the Company in the first quarter of 2014 and applied prospectively. There was no impact to our consolidated financial statements due to the adoption of this guidance.
	On May 28, 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. This standard is effective for the Company beginning in 2017 and allows for either full retrospective adoption or modified retrospective adoption with cumulative effect recognized at the date of initial adoption. Early adoption of this standard is not allowed. The Company is currently evaluating the impact of the adoption of ASU 2014-09 on its financial statements.
	In June 2014, the FASB issued Accounting Standards Update 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period: Topic 718 (ASU 2014-12). The standard states that a performance target in a share-based payment that affects vesting and that could be achieved after the requisite service period should be accounted for as a performance condition. This standard is effective for the Company beginning in 2016 and early adoption is permitted. The Company is currently evaluating the impact of the adoption of ASU 2014-12 on its financial statements.

[1]	In 2014, certain products were moved from the Candy category to the Health, beauty & general category to align them with the industry classifications used by the National Association of Convenience Stores. The 2013 presentation has been realigned to reflect these changes. Without the changes, net sales for Candy and Health, beauty & general products would have been $139.3 million and $81.6 million for the three months ended June 30, 2013, respectively. Net sales for Candy and Health, beauty & general products would have been $263.2 million and $153.6 million for the six months ended June 30, 2013, respectively.
