here is what happened to me
Listed item (Apple Computer) as PayPal only and local pick up (due to enormous size of box)
Received a call after buy it now was processed, buyer came and I let item go AFTER I saw the funds in my PayPal account. (Buyer had an account with 820 feedback rating)
10 minutes later an email was received from PayPal saying the funds had been reversed and a dispute opened.
It transpires that I'm not covered by PayPal because the item was "collected in person" and I'm not covered by house insurance under a "No payment in case of loss by deception" clause, so Im stuffed.
I didnt know that a) payments in PayPal could even be reversed and b) collection in person wasnt covered by Sellers Protection
Another ebayer was had the same way by the same people 30 mins after me. they collected a big TV from them and reversed the payment
PLEASE DONT LET THIS HAPPEN TO YOU
