I'm not positive about this, but I think the seller has the right to cancel any bid that he might not like. For instatnce, if a bidder has bad feedback he can delete the bid. Try writing the seller and explain. They might be able to help you.

Hope it all works out. The worst that can happen is you will get 1 bad feedback, which you can respond to.

Maybe the price will not go to high and you will win.
