I can't believe this happened, but it did! I was bidding on a cue at Proficient/Cue Auctions, and was high bidder with about 2 minutes to go but not by much. I decided to enter a higher maximum bid to get a little margin to ward off "snipers" (last-second bidders) and when I did, I outbid myself!! Instead of just recording that I entered a higher maximum bid, my new bid exceeded my old maximum bid!!! This really sucks...I would have won the cue for $58 less than I now have to pay for it! This certainly isn't the seller's fault, so I appealed to Proficient/Cue auctions, but they said there was nothing they could do because the auction had ended, and that "the software allows you to bid against yourself in order to reach reserves that are not met, or to raise your current bid...". Now I know...just wanted to let all of you know too. Live and learn.
