I sold a laptop as-is on eBay. The buyer emailed me that they got it ok and it worked fine. A couple days later, they decide it wasn't "described well" and got their credit card company to do a chargeback.
PayPal not only refunded them the money out of my account, the buyer has not returned the laptop!
Good luck to those that have been scammed. And Beware to those who haven't. The seller protection is horrible and they will most likely back the buyer up.
