Here's how I win things on eBay. It's called sniping, and there is software that can do it for you, but I've always done it manually. The images are screen shots from an auction I won yesterday.
The eBay system allows you to set any high bid amount you want, and raises bids by smaller increments depending on the leader's high bid. So, I prepared my bid at $168.52, submitted it with less than ten seconds to go and my leading bid turned out to be $26.
Usually, it's Game over! And that, my friends, is the art of the snipe. I had paid for the item before the other bidder even knew what happened.
