Tell him to send you the money before you take it off of ebay. Otherwise he could be trying to get you to dump your auction so he can sell something of his. I had some yahoo do this to me before, asked me to end the auction early and when I did he didnt answer any emails, and I came to find out he was selling something similiar to what I had been selling. So since he didnt bid, I couldnt give him any negative feedback.
