Never knew Overstock.com had auctions. Found some dirt cheap stuff. Put bid in with 20seconds left and became high bidder. Any time there is a new high bidder with less than 10 minutes to go a 10 minute time extension is given to the auction. Somebody else bid, became high bidder, and 10 more minutes was added. F-IT. This was taken from their FAQ: Question Auction Time Extensions Answer If an auction receives a bid that creates a new high bidder within 10 minutes of the auction closing time, the auction will be extended for an additional 10 minutes from the time it was originally scheduled to close. All bidders will receive an auction extension notice via email. Note: The auction will continue indefinitely until 10 minutes have passed without a new high bidder.
