From November 15th-December 6th, 7th on Sale is back with a fundraising event to benefit HIV and AIDS organizations (and maybe your closet, too!).

Along with Ebay, 7th on Sale has created a website, 7thOnSale.Ebay.com, which will host seven-day auctions that launch daily, hawking donated items from designers like Marc Jacobs, Calvin Klein, Coach, and Vera Wang, among many others. All bids start at 10% of retail price, and MAC has agreed to match every dollar raised at the auctions, up to $500,000. Not to mention that 100% of all proceeds are being donated. Sounds like a charitable fashion bonanza!
