The bidding history, shown on the eBay auction item page, lists everybody who is bidding on an item. You can see how often and at what time bids are placed, but you can't see how much each bidder bids until the auction ends.

Pay attention to the times at which bidders are placing their bids; you may find that, like many eBay users, the people bidding in this auction seem to be creatures of habit — making their bids about once a day and at a particular time of day. They may be logging on before work, during lunch, or after work. Whatever their schedules, you have great info at your disposal in the event that a bidding war breaks out: Just bid after your competition traditionally logs out, and you increase your odds of winning the auction.

Early in an auction, there may not be much of a bidding history for an item, but that doesn't mean you can't still check out the dates and times a bidder places bids. You can also tell that a bidder practices sniping — that rapid-fire, final flurry of bidding — if his or her bid zips in during the last few minutes (or even seconds!) of the auction. You may have a fight on your hands if the bidder is seasoned at sniping.
