Abstract: A method enables a seller to bid in multiple electronic reverse auctions. The method includes determining auctions for which the seller is eligible, informing the seller of the eligible auctions, and receiving a selection indicating which of the eligible auctions the seller will participate in. The method also includes receiving a single bid from the seller, and applying the single bid to each of the selected auctions. Based upon the single bid, as well as bids from other sellers, winnings are determined for each of the selected auctions.
