I'm no ebay expert, but something about that smells to me. You might consider cash only if someone other than the buyer picks it up. Or maybe even cash only for ANY pickup. I only worry about the 'proof of delivery' that you would lose when it gets picked up. It would suck to have a paypal chargeback a month later and no way to prove that it was picked up by a 'friend'. Consider that your buyer had NO feedback before your transaction.
