The seller is just upset about the price and you deserve to own this jersey. Just last week my I sold some of my kid rock concert used drum sticks and I was unable to end the early due to a bid. The pair of sticks sold for $9.99 which is way under value. As a seller with over 600 positive feedback, all 100%, I still packed the sticks up, and shipped them to the winning bidder.

The seller in your case deserves negative feedback! If they want to make it up to you they need to paypal you what your bid was because as far as I see it they're BS'ing you.

If you decide you're unable to come to a compromise just tell them the hell with it and tell them to leave you positive feedback. Once they do they leave them negative feedback!
