... then jumped up. All after one bidder retracted his bid. But the other bidders 8-9 bids (what he needed to reach the others bidder) were still there. Theoretically, since the seller, if he was watching, knew the bids were up to 168 dollars, could have asked a friend to bid it up to something a bit below that, making the existing bidder have to go back up there. I am NOT suggesting that's what is happening here, but after the top bidder cancels out, it sure leaves the other bidder vulnerable! Even though it was at 9.99, his proxies were up to 168, leaving him like a sitting duck!
