I lost the bid by $75 because I was away from my desk.
If your serious about winning, why would you not be on line at least 10 minutes before the end of auction, and stay there?
Whatever the reason, the only alternative if you must go off line, is to plug in your max bid before you abandon the ship.
Still there is no guarantee, $75 is just a guess based upon the winning bid, who is to know the true resolve of the winning bidder.
They looked worth it, excellent finish... good luck next time
