U.S. AUTO PARTS NETWORK, INC. NAMES TED SANDERS, CHIEF FINANCIAL OFFICER

Sanders brings 25 years of online, retail, technology finance experience

CARSON, CA – February 17, 2009 – U.S. Auto Parts Network, Inc. (Nasdaq: PRTS), a leading online provider of aftermarket auto parts and accessories, today announced that effective February 16, 2009, the Company has appointed Theodore R. (“Ted”) Sanders, Jr. as Chief Financial Officer.

Mr. Sanders brings over 25 years of diversified financial and operational management experience in both public and privately held companies and “Big Four” public accounting to US Auto Parts. He joins the Company after most recently serving as Chief Financial Officer of ViewSonic Corporation.  Prior to joining ViewSonic Corporation, from 1997 to 2007 Mr. Sanders served as Chief Financial Officer of public company PC Mall, Inc., a marketer of technology products with over $1.2 billion in revenue in 2007, where he helped the company grow organically and through acquisition to offer over 125,000 different products to over ten million customers. Mr. Sanders also successfully off-shored and managed certain sales and back-office functions to Canada and the Philippines.

Prior to PC Mall, Mr. Sanders was the controller and Director of Finance for BAX Global, a $1.7 billion subsidiary of The Pittston Company, a global business and security services company. At Pittston, he also served as the Director of Internal Audit.  Mr. Sanders started his career at Deloitte & Touche LLP and is a Certified Public Accountant.

“Ted’s background is a perfect complement to U.S. Auto Parts,” said Shane Evangelist, Chief Executive Officer.  “He comes from an organization where he optimized a complex, multi-national e-commerce business model - like ours, and he maximized that model within a low-margin industry. I am confident he will excel at coordinating the constantly moving cost thresholds and logistics of drop-ship and stock-ship distribution as he has previously, as well as the variable cost model of off-shore provision of services. Ted will be a great asset to U.S. Auto Parts and we are pleased to have him on the ground.”

"I am very excited to join an innovative company like U.S. Auto Parts at a time when the market is poised to take advantage of USAP’s products and services," said Mr. Sanders. "I think U.S. Auto Parts has tremendous potential and I look forward to rolling up my sleeves and partnering with the rest of the management team."
