Did the seller post a refund policy on his listing, Matt? Ebay will hold him to that.

Sounds like a real idiot. In all the years I have been on Ebay, I ran into only one. He didn't ship. Swore he had. Then shipped the wrong item BROKEN. When I posted negative feedback, he openly called me a liar and said I was trying to steal his item.
Next day he offered to take down the negative feedback if I would take down mine. I never responded. My money was refunded but after repeated requests he never sent me an address to return the item. It was shipped from a warehouse somewhere with no return address. But I paid thru Paypal.
