Item 9. Regulation FD Disclosure

The Registrant will be presenting at the Fifth Annual Goldman Sachs Internet Conference on May 26, 2004, the Friedman, Billings Ramsey Eighth Annual Growth Investor Conference on June 2, 2004 and at institutional meetings with Credit Suisse First Boston on June 10, 2004. A copy of the Registrant’s presentation materials, appearing as Exhibit 99.1, is furnished and not filed pursuant to Regulation FD.

The presentation included as Exhibit 99.1 contains adjusted EBITDA, net merchandise sales and certain ratios that use net merchandise sales which may be considered non-GAAP financial measures. The Registrant uses adjusted EBITDA as a means to evaluate its performance period to period without taking into account certain expenses, particularly stock-based compensation expense, which may fluctuate materially due to fluctuations in the price of the Registrant’s common stock both on a quarterly and annual basis, and does not consistently reflect the Registrant’s results from its core business activities. The Registrant also uses net merchandise sales as a metric for operating its business. Variable costs such as fulfillment and customer service labor expense, order processing costs such as credit card and bank processing fees and business management costs such as marketing department staffing levels are related to the amount of sales made through the Registrant’s platform, whether or not the Registrant records the revenue from such sales. The Registrant believes that investors will have a more thorough understanding of its historical expenses and expense trends if they have visibility to both GAAP net revenue as well as the non-GAAP financial measure net merchandise sales and the percentages that such expenses bear to net revenues and net merchandise sales. These financial measures should be considered in addition to, and not as a substitute for, or superior to, other measures of financial performance prepared in accordance with GAAP. These financial measures included in this presentation have been reconciled to the nearest GAAP measure as is required under SEC rules.

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