A friend of mine told me about this tool called Auction Sniper that watches your bid on an item and places a winning bid at the last possible moment, often seconds before the end of the auction, thus giving the other bidders no time to outbid you. This is useful if the auction ends at 2 in the morning.

This is particularly timely, as I’m trying to buy a Microsoft Zune on eBay and keep on getting out bid last minute.
