yeah, pay him a visit and dont forget the brick!
I have been fortunate with eBay I quess. 8 years, over 500 transactions (I am not a business, just buying and selling cars, bikes, parts, garage cleanouts and stuff for friends). I have a positive feedback of 99.9% with only 2 negatives in 8 years and they were both from people who refused to pay me. I am very strict with my payment options, Paypal only. I also choose the option that bidders must have at least 1 feedback, no negative feedback in X amount of days and I think the last on is bidder must not be bidding on X amount of auctions at the same time. I also watch my bidders, if anyone even seems suspicous I remove their bid and block them from bidding from there on out. Sorry to hear some of you guys experiences but eBay has been pretty good to me over the last 8 years
