I thought about something while reading and getting ready to post again to this thread. IF the seller listed something in error or chose to end the auction early d/t unknown whatevers, they have the right to end the auction early as i had this once done to me. THe seller emailed every bidder and explained the situation and was later relisted with the corrected information and a reserve. Once a particular auction has ended, I don't believe that they have the right to back out of it, as it is a binding auction if I remember right. At least that is what it says when you have to confirm that you want to place x amount for your bid. What's fair is fair and I think that her leaving you a negative feedback is not the wisest of things for the seller to have done. I would really pursue this, regardless if she meant it in error or not. If that was the case, can't imagine her taking the time to make sure she gave you the negative feedback. I have only purchased from ebay, well over 400 transactions, and I have only gotten burned once (the seller got my money and the product) I had emailed ebay and it wasn't long after that, the seller was no longer a listed seller (apparently this seller had a run of these same complaints). I wish you the best of luck on this.
