girlfriend won an auction, used paypal, sent an e-mail to the seller, sent another one a week later, never recieved a response. then the item showed up.
almost a month after the auction ended and she had paid with paypal, she gets an e-mail through ebay accusing her of being a non-paying bidder! she e-mailed the guy back, gave him her paypal info, and told him she had paid. the next day she got a reply that said "Done." no "sorry for the confusion" or "i must have overlooked that, sorry," nothing. so the assholes work both ways on ebay.
