It only takes getting burned once to get your ducks in a row for future transactions. Set up the shipping tool on your Paypal account and ship directly from there. It's convenient, quick, and provides instant tracking info to PP and the buyer. I had shipped some merchandise to Canada via USPS priority (using PP) and the buyer stated they never recd the item despite the fact that CAN post provided a delivery confirmation. My auction clearly stated that once it was shipped and tracking was provided, that I wasn't responsible for lost shipments and claims would have to be filed with the shipping company. Based on his mannerisms, I truly think he was trying to scam me, right down to threatening to "send some friends to pay me a visit".... that part really cracked me up! ... he filed a dispute with PP and they denied it within a day since the tracking info showed it was delivered. He then filed another dispute stating that the item wasn't as described, which then locked up the funds. He even supplied a fake tracking number to make it look like he was sending the item back to me. After a couple of calls to PP, they dropped the claim in my favor.
