If no bidders meet the reserve price, neither the seller nor the high bidder are under any further obligation. You can't use reserve prices for Dutch Auctions , and items with reserve prices are not displayed in the Hot Items section. Bidders' email addresses won't show up on the item or bidding-history screens. When the auction is over, only the seller will know who bought the item. This option can't be used with Dutch Auctions.
Sellers start by listing a minimum price, or starting bid, and the number of items for sale.
Bidders specify both a bid price and the quantity they want to buy. If there are more buyers than items, the earliest successful bids get the goods. Higher bidders get the quantities they've asked for. Bidders can refuse partial quantities. Check out an example .
