Exhibit 99.4

Unaudited Pro Forma Combined Financial Statements

On September 10, 2007, GSI Commerce, Inc. (the “Company”) completed the acquisition of Accretive Commerce, Inc. (“Accretive”). Pursuant to an Agreement and Plan of Merger dated as of August 16, 2007 among the Company, Blue Route, Inc. (“Newco”), a wholly-owned subsidiary of the Company, Accretive and certain of the principal stakeholders of Accretive, Newco merged with Accretive and Accretive survived the merger as a wholly-owned subsidiary of the Company. The accompanying unaudited pro forma combined financial statements give pro forma effect to the Company’s acquisition of Accretive, which closed on September 10, 2007, assuming a purchase price of $98.6 million in cash, including acquisition costs of $1.1 million, using the purchase method of accounting.

The following unaudited pro forma combined financial statements were prepared using the historical consolidated financial statements of the Company and Accretive. This information should be read in conjunction with, and is qualified in its entirety, by the consolidated financial statements and accompanying notes of the Company and Accretive incorporated by reference into this current report.

The pro forma adjustments related to the acquisition are preliminary and do not reflect the final purchase price or final allocation of the excess of the purchase price over the net book value of the net assets of Accretive, as the process to assign a fair value to the various tangible and intangible assets acquired has not yet been completed. Final adjustments could result in a materially different purchase price and/or allocation and of the purchase price, which will affect the value assigned to the tangible or intangible assets and amount of depreciation and amortization expense recorded in the consolidated statements of operations. The effect of the changes to the consolidated statements of operations will depend on the final purchase price and the nature and amount of the final purchase price allocation and could be material.

The accompanying unaudited pro forma combined statements of operations for the fiscal year ended December 30, 2006 and the nine-months ended September 29, 2007 assumes that the acquisition took place on January 1, 2006, which was the first day of fiscal 2006. The unaudited pro forma combined statement of operations for the fiscal year ended December 30, 2006 combines the Company’s audited consolidated statement of operations for the fiscal year ended December 30, 2006 with Accretive’s audited consolidated statement of operations for the year ended December 31, 2006. Accretive’s revenues, expenses and net income for the one day ended December 31, 2006 were immaterial. The unaudited pro forma combined statement of operations for the nine-months ended September 29, 2007 combines the Company’s unaudited consolidated statement of operations for the nine-months ended September 29, 2007 with Accretive’s unaudited consolidated statement of operations for the period from January 1, 2007 to September 9, 2007. Accretive’s results of operations are included in the Company’s consolidated statement of operations beginning on the acquisition date of September 10, 2007 through September 29, 2007. A pro forma balance sheet is not included as the balance sheet effects of the acquisition are reflected in the Company’s Condensed Consolidated Balance Sheet as of September 29, 2007 included in the Company’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 8, 2007. Reclassifications have been made to the consolidated statements of operations of Accretive in order to conform to the Company’s financial statement classifications as described in “Note 2 — Unaudited Pro Forma Adjustments.”

The pro forma financial information is based on the estimates and assumptions set forth in the notes to such information. The pro forma financial information is preliminary and is being furnished solely for information purposes and, therefore, is not necessarily indicative of the combined results of operations or financial position that might have been achieved for the dates or periods indicated, nor is it necessarily indicative of the results of operations or financial position that may occur in the future.

NOTE 2—UNAUDITED PRO FORMA ADJUSTMENTS

The pro forma adjustments related to the acquisition are preliminary and do not reflect the final purchase price or final allocation of the excess of the purchase price over the net book value of the net assets of Accretive, as the process to assign a fair value to the various tangible and intangible assets acquired has not yet been completed.

	(a)		Represents the elimination of intercompany management fees paid by Accretive to its parent. The Company is not required to pay these management fees.

	(b)		Represents $3,521 of additional amortization expense resulting from the preliminary allocation of a portion of the purchase price to intangible assets primarily consisting of contractual customer relationships and non-compete agreements with certain key employees and selling shareholders of Accretive. The contractual customer relationships are amortized in proportion to the expected future cash flows over the lives of the contracts and the non-compete agreements with certain key employees and selling shareholders are amortized straight-line over the terms of the non-compete agreements. These intangible assets have useful lives of three to five years.

	(d)		Represents the income tax effect of the pro forma adjustments, recorded at the Company’s estimated statutory rate of 38.2%.

The pro forma adjustments included in the unaudited pro forma combined statement of operations for the fiscal year ended December 30, 2006 are as follows:

	(e)		Represents a reclassification of Accretive’s reported revenue.

	(f)		Represents a reclassification of Accretive’s reported cost of revenues.

	(k)		Represents $7,989 of additional amortization expense resulting from the preliminary allocation of a portion of the purchase price to intangible assets primarily consisting of contractual customer relationships and non-compete agreements with certain key employees and selling shareholders of Accretive. The contractual customer relationships are amortized in proportion to the expected future cash flows over the lives of the contracts and the non-compete agreements with certain key employees and selling shareholders are amortized straight-line over the terms of the non-compete agreements.
