Recently, some mainstream e-commerce web sites have apparently achieved the same end on a much broader scale, by using \"pay-per-bid\" auctions to sell items, from video games to bars of gold.  In these auctions, bidders incur a cost for placing each bid in addition to (or sometimes in lieu of) the winner's final purchase cost.  Thus even when a winner's purchase cost is a small fraction of the item's intrinsic value, the auctioneer can still profit ","authors_text":"Georgios Zervas, John W.
