Item 2.02  RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

      On April 25, 2007, GSI Commerce,  Inc. ("we" or the "Registrant") issued a
press  release  announcing  our results for our 2007 fiscal first  quarter ended
March 31, 2007 and certain  other  information.  A copy of the press  release is
furnished as part of this report and incorporated herein by reference.

      The press  release  (included  as  Exhibit  99.1)  contains  the  non-GAAP
financial  measures of merchandise sales,  adjusted EBITDA,  non-GAAP net income
and free cash flow. We also discuss certain ratios that use these measures.

      We use these  non-GAAP  financial  measures for financial and  operational
decision  making and as a means to evaluate  our  performance.  In our  opinion,
these non-GAAP measures provide meaningful  supplemental  information  regarding
our  performance.  We believe that both  management  and investors  benefit from
referring to these non-GAAP  financial measures in assessing our performance and
when  planning,   forecasting  and  analyzing  future  periods.  These  non-GAAP
financial  measures also  facilitate  management's  internal  comparisons to our
historical  performance and liquidity as well as comparisons to our competitors'
operating  results.  We believe these non-GAAP  financial measures are useful to
investors both because (1) they allow for greater  transparency  with respect to
key metrics used by management in its financial and operational  decision making
and (2) they are used by  institutional  investors and the analyst  community to
help them analyze the health of our business.

      Merchandise  sales. We define merchandise sales as the retail value of all
sales  transactions,  inclusive  of freight  charges and net of  allowances  for
returns and  discounts,  which flow through our platform,  whether or not we are
the seller of the  merchandise  or record  the full  amount of such sales on our
financial  statements.  We consider  merchandise sales to be a useful metric for
management  and  investors  because  a  significant  portion  of our  sales  and
marketing  expenses,  including  fulfillment and customer service labor expense,
order  processing  costs  such as  credit  card  and  bank  processing  fees and
organizational costs such as business  management,  are related to the amount of
sales made through our platform,  whether or not we record the revenue from such
sales.  As a result,  we use this  metric  as part of our  revenue  and  expense
forecasting  process and for capacity planning purposes.  We monitor this metric
on a daily basis and  consider it to be a critical  measure of the health of our
business.

      Adjusted  EBITDA.  We define  adjusted  EBITDA as income  from  operations
excluding stock-based  compensation and depreciation and amortization  expenses.
We consider  adjusted  EBITDA to be a useful metric for management and investors
because it  excludes  certain  non-cash  items.  Because  of  varying  available
valuation  methodologies,  subjective assumptions and the variety of award types
that  companies  can use when valuing  equity awards under SFAS 123R, we believe
that viewing income from operations excluding  stock-based  compensation expense
allows   investors  to  make  meaningful   comparisons   between  our  operating
performance  and those of other  businesses.  Because we are growing rapidly and
operate in an emerging and rapidly changing industry,  we believe that our level
of  capital   expenditures  and  consequently  the  level  of  depreciation  and
amortization  expense  relative to our revenues  could be  meaningfully  greater
today  than  it  will be  over  time.  As a  result,  we  believe  it is  useful
supplemental  information to view income from operations excluding  depreciation
and  amortization  expense as it  provides a potential  indicator  of the future
operating margin potential of the business.


      Non-GAAP net income. Beginning with this release, we are defining non-GAAP
net income as net income plus stock-based  compensation expense and amortization
of  acquisition-related   intangibles  minus  cumulative  effect  of  change  in
accounting  principle  related to the adoption of SFAS 123R and  plus/minus  the
provision/benefit  for income  taxes.  This  figure is then taxed at our current
annual  effective  tax rate to arrive at non-GAAP  net income.  We believe it is
useful to exclude stock-based  compensation expense from non-GAAP net income for
the same reason we exclude it from adjusted  EBITDA.  We believe it is useful to
exclude amortization of  acquisition-related  intangibles because in our opinion
the  benefits of these  assets  could  exceed the  amortization  period and this
supplemental  view  enables  management  and  investors  to measure the business
without this potential  effect.  The gain we recorded from the cumulative effect
of change in  accounting  principle  related to the  adoption of SFAS 123R is an
item we view as  non-recurring  in  nature.  We believe it is useful to view net
income  without  the  benefit of this  non-recurring  item.  We exclude the GAAP
income tax  provision  in order to compute  the  non-GAAP  pre-tax  income.  The
non-GAAP  pre-tax income is then taxed at our current annual  effective tax rate
to arrive at non-GAAP net income.

      Free cash flow. We define free cash flow as net cash provided by operating
activities   minus  capital   expenditures,   including   capitalized   software
development.  We consider free cash flow to be a liquidity measure that provides
useful  information  to  management  and  investors  about  the  amount  of cash
generated by the business that, after the acquisition of property and equipment,
including  information  technology  infrastructure,  can be used  for  strategic
opportunities,   including   investing  in  the   business,   making   strategic
acquisitions  and  strengthening  the balance sheet.  Analysis of free cash flow
also  facilitates   management's   comparisons  of  our  operating   results  to
competitors'  operating results. A limitation of using free cash flow as a means
for  evaluating  our  performance  is that free cash flow  reflects  changes  in
working  capital  which is impacted by  short-term  changes in cash flow and the
seasonality   of  our  business   which  may  not  be  indicative  of  long-term
performance.  Another  limitation  of free cash flow is that it  excludes  fixed
assets  purchased  and placed in service but not paid for during the  applicable
period. Our management  compensates for this limitation by providing information
about  capital  expenditures  on the  face of the  cash  flow  statement  and in
supplemental disclosures in our Forms 10-K and 10-Q.

      These  financial  measures are not intended to be  considered in isolation
of, as a  substitute  for or superior  to our GAAP  financial  information.  The
non-GAAP financial measures included in the press release and to be included the
conference  call have been reconciled to the nearest GAAP measure as is required
under Securities and Exchange Commission rules.


      As used herein,  "GAAP" refers to accounting principles generally accepted
in the United States.
