What I do is I have a number in my head and wont go past that. I lost the wagon for 50 because we bid against each other from 600 up in 25 dollar increments. My number was 1,000 and he took the last bid at 1,025 which meant I would have went 1,050 but who knows how much it would have went up to. Another thing I think of is what if he was bidding just to run me up in price so I walk and let them have it. There will be others.
