I would really be pissed if I was the seller. I was watching those two auctions, one for the hands and the other for the body and gauntlets. He was probably the first guy to put up some wolf parts in the us. The hands obviously went for .99 and the body and gauntlets for something like $50 with shipping, i was kicking myself for missing those auctions. Anyway, yeah those items oddly went for very low prices and I wouldve hated to let them go for so cheap as Im sure he did, or in your case didnt. That really sucks man, theres to many douche bags running around our hobby.
Also that seller recently won two of my auctions for some pred 2 gear. He won the kneepads and shin armor, he paid around $30 combined for those! $30 for some kneepads and shin gaurds! The guy is a bit wacky both ways
Well, you know I've heard some folks on evilbay have multiple accounts and bid on their own auctions to get the bids up. If it doesn't sell for what they want, they win the bid themselves by snipping the low bidder. Then they leave themselves positive feedback. So maybe he did think he was leaving himself some feedback
either way I would leave him some good ole neg unless he can work out something with you.
