Enter, "Mr. Too Much Time On His Hands." This individual that had no intention of winning the bid would sit and put in bids, sometimes up to 100 bids. When he would see the bid increment change to an uneven amount he would know he had bumped up against my high bid. Then he would stop.

OK, This is getting really scarey and educational. First I find that there are bidders out there with Internet connections and programs that can bid as late as 5 seconds and now you point out how my strategy of bidding odd amounts can lead to an unscrupulous seller placing multiple bids to find the high limit of my bid and stopping just short.

I might have to rethink some of my strategy.
