I've sold a belt 3 weeks ago to a bidder with 0 feedback. He/she first couldn't transfer the money, then wanted to send me the money in an envelope (wasn't that much). I've opened an unpaid item claim now. But that's not my intention to trade on ebay.
I think ebay is for some people a place to look and want, but not to pay
My next auctions will be defined with the option that bidders with 0 feedback will be refused. This is possible.
ebay is the largest marketplace in the internet i know. If we use this marketplace we are forced to accept that some people suck...as it is in real life.
Hope you get your item (paid with paypal?) or even get your money back.
