A sponsor provides items to a residual value bidding system, which allows an auction to auction the items to bidders. Value expended to bid on the item, such as through a pay-per-bid model may be returned as a giftcard to the sponsor's store. Incentives may be used to encourage bidding, such as a coupon that gains value as more bids are placed. The coupons may be time dated to encourage immediate redemption. Sponsored auctions may also be limited to geography or demographics. |
