I keep seeing people posting tips for haggle.com. Many of them are saying that marathon bidding is the best way to go. I'm not convinced that is entirely true. It seems to me that the best approach is to get a general idea of how much a specific item is generally going for on average. When the auction nears that point and the bidding slows, I would suggest trying to sneak in some last second bids where you think the auction is most likely to end. Let the "marathon bidders" speed up the auction for you and allow you to conserve your bids! Your more likely to win if you do your homework first. If you jump head first into any auction you'll probably end up out of bids and out of money! Worst comes to worst, you wait and lose an item. The best part about haggle.com is that you will most likely have another chance at the same item very soon! Be smart and bid wisely!
