TORRANCE, CA, August 27, 2004 – eCOST.com, Inc. (Nasdaq: ECST), a wholly-owned subsidiary of PC Mall, Inc. (Nasdaq: MALL), today announced that it has priced its public offering of 3,465,000 shares of its common stock at $5.80 per share, a reduction from the range of $9.00 to $11.00 per share shown in the Company’s preliminary prospectus, with estimated net proceeds to the Company of $15.8 million, after deducting underwriting discounts and estimated offering expenses. The shares are being offered by the Company pursuant to a registration statement that was declared effective by the Securities and Exchange Commission today.

Nasdaq has preliminarily indicated that both of these requirements will be satisfied if the closing bid price on the first day of trading is equal to or greater than the initial public offering price. At the initial public offering price of $5.80 per share, the market value of the Company’s publicly held shares (excluding any shares purchased by one of the Company’s officers in the offering) would be $20,010,000. If Nasdaq determines that its initial listing standards are not met, the offering will not be consummated.
