Just a heads up to all the honest sellers out there. If a user called chinky250 bids for your item, cancel their bid. They win your item, then don't pay and leave negative feedback. They bid for a PSP game that I had sold, and I noticed they also do the same on someone else who was also selling a game.
On that point, there really needs to be a way for Ebay to help us sellers remove such feedback, which clearly have nothing to do with the transaction.
