How it works is the person who wants to bid on an item decides a maximum amount that he or she is willing to pay for it in advance, and bids this amount. That bid is hidden in our system. As other bids are made, the system automatically increases the person's bid by previously specified increments until the maximum amount is reached. If the bidder is monitoring the auction, at this point he/she can give up or choose to increase his bid. You don't have to continually monitor an auction to win an item, and can bid on several items at once.
