If you read Article 2 of the Uniform Commericial code, it states
3) Such a sale is with reserve unless the goods are in explicit terms put up without reserve. In an auction with reserve the auctioneer may withdraw the goods at any time until he announces completion of the sale. In an auction without reserve, after the auctioneer calls for bids on an article or lot, that article or lot cannot be withdrawn unless no bid is made within a reasonable time. In either case a bidder may retract his bid until the auctioneer's announcement of completion of the sale, but a bidder's retraction
does not revive any previous bid.
In any normal auction (and I assume ebay auctions), once you are outbid, the offer (bid) is no longer an offer. Ryan, in your case, bidder A had no obligation to buy your item at any price, and was perfectly within his rights to try and get it at a low price. You, of course, had no obligation to sell it to him at a low price.
