OMG, I did exactly the same thing!!! I didn't realise until the next morning when I saw the notification that I'd won it. I thought it weird that I got it when I only bid $35, when I have seen them sell for over $200. Then I saw my maximum bid amount.......$35,000!!!! Thankfully it sold for $52, so it wasn't so bad. I nearly died because I would've had to sell my liver to pay for it otherwise. I have nearly done it a few more times, but thankfully noticed the 5 or SIX figures before I hit the second button. One time I did submit with 6 figures, but fortunately had enough time to find the cancel bid page (it had 3 minutes to go). I felt bad because by doing that I saw what the highest bidders maximum bid was, which was more than I was prepared to pay, so I entered a bid under that so I didn't risk getting into trouble by retracting a bid and not rebidding. I've bought LOTS off that seller and I know he sits and watches his auctions finish so I think he would've seen the higher bid, then watch it go down again. I didn't mind letting him get the slightly higher amount as he's looked after me plenty of times.

I really shouldn't bid in the dark when I'm 3/4 asleep. Those comma's and full stops look the same through tired eyes LOL!
