If that bidder comes through with the cash, you did very well on that auction my friend. Congrats But like it was said before, that guy has -2 feedback. So be careful.
The high bidder is probably full of it and jacked the price up. Its a shame he probably ruined your auction.
His feedback said that he told other sellers that he didn't have any intention of paying them, what a retard. I guess its "fun" for him to cost other people money.
