same thing happened to me. I was tracking one for a week. I made sure I was on the computer write down to the last minute. I stop bidding after it flew past 140.00. I guess if you want it bad enough you can put down 1000 for your highest bid.
I can get it for 140 retail, so I am trying to get it for less. It always just seems to go past where I am bidding. If I bid 75 it ends at 80. If I bid 100 it ends at 105.
