I just sold my early 2011 Macbook Pro on eBay. The buyer contacted me to ask if I can lower to Buy it Now price, I negotiated with him a bit and then did that. As soon as I lowered the price he paid for it and the money is now in my bank account (from paypal). How do I know he's still not a fraudster? How can I protect myself from him not returning the laptop or anything like that and then asking for the money back? The reason I'm asking is because after buying it he said he's buying it to get his mind off two of his family members dying in a car crash. This makes it sound a bit like a fraud for some reason. Can someone please help? Should I send it to him or should I cancel the transaction?
