eBay is testing a new promotion called "Big Deals" in which sellers offer "limited quantities of specific products at really good prices" that are available for one day only, or until supplies run out. The Big Deals landing page will be available with new deals each day for the next two weeks. The site appears to be based on the same concept as Woot.com, a site that sells only one product for one day (http://www.auctionbytes.com/cab/abn/y04/m12/i13/s03).

eBay worked with ChannelAdvisor, an eBay Certified Provider, who helped secure a portion of the product offerings from sellers. For the test, eBay solicited deals from select sellers who met specific criteria: They are experienced sellers who are registered in the U.S; have the ability to supply large quantities of a single product; have a public Feedback profile with a score of 100 or more and is 98% positive or better; and have a PayPal Premier or Business account.

eBay said the results from the pilot will help them determine whether to open participation to a larger group of sellers.
