Barter Auctions
A Barter Auction is an auction where the auctioneer is willing to accept barter offers from bidders. A barter offer can consist of anything the bidder can describe. This could be an offering of some other item in exchange for the auction item. Or it could be an item plus some additional cash offering in exchange for the auction item. The auctioneer is able to choose whichever offer he wants to accept.
