It's easy. You really want it, how much are you willing to go. In that last few seconds place your bid, say $5, $10, or $20 higher than you were going to bid. The system will only bid up the small increments not the entire amount you placed because that is your maximum. The guy you are going against probably has a high bid already in place. Me, I would do it in the last 8 seconds to give system to counter bid. It's a crap shoot...all in the timing.
