OMG OMG OMG
Dude,
The SAME thing just happened to me - I have begun to lost faith in eBay as an ethical place to buy / sell goods. And don't even get me started w/ Paypal. I could fill this entire page w/ horror stories, but I'll keep it short and sweet in regard to my recent macbook sale.
So I put the macbook up for auction - ten day auction, starting at 1 cent, no big deal. Auction ends - i expect to receive payment as usual, etc. Instead, i get ebay messages from the winner in broken english asking if his friend can send me the paypal money and if i mind shipping the computer to his "mum" in Norway. For those of you who don't have a lot of ebay experience FYI, do NOT do this - trust me once you get paid w/ paypal, you can still get it revoked - I have sold things, then 2 months later, paypal takes it away due to buyer chargebacks and even though i have receipts / tracking numbers. In any case, back to the story - so i relist the item. Then it gets bought buy a buyer w/ decent feedback - okay cool. I await payment / messages from him. Oh btw, i offer free shipping if people send a check / money order so i can avoid chargeback risk. Soooooo... then ebay sends me some generic email about how someone got ahold of the buyer's account and blah blah blah auction is canceled. Okay - fine. So I re-list a 3rd time. Finally an ethical person buys. They pay w/ check to get free shipping. I'll ship the computer on monday hoorah.
But in the end, I had to sell something 3 times before I got an ethical buyer - so one out of three? Like i said, I'm really losing faith in eBay/paypal. If an alternative arises, i'm there.
