I've bought something from you, but can't remember what lol. I've purchased SO much!!!

I'd open a case with ebay. You have nothing to lose. Ebay does suck now but I'd give it a shot. Explain your case with ebay and provide the picture. Maybe with some contact from Ebay the guy will pay. It's about the principal, not the money.

Ebay does a terrible job in site upkeep, and policing the site as well. Unfortunately it's the biggest source still.
