"The "Art" of Sniping
How does sniping work? To understand the details behind sniping, you need to understand proxy bidding. After the seller has set an opening price and an increment by which bidding will increase, bidders then place the highest bid they're willing to pay for the item (this amount is kept secret from all other bidders and the seller). Subsequent bidders do likewise; every time you're outbid, however, the proxy system increments the bid to put you back on top, continuing until someone reaches his limit. At the end of the allotted time for the auction, whoever has the highest bid wins.

Snipers eschew the proxy bidding method in favor of a single bid. They wait until the last seconds of an auction and jump in to place a bid, hoping that it's higher than everyone's high bid. If they've guessed correctly, they can walk away with the goods for much less than they're worth without giving the other bidders a chance to place another bid."
