You are still responsible for delivery even if the screwup is the fault of the buyer. If the buyer moved months ago and did not change his address in Paypal the USPS will not forward the package. He files as not delivered on ebay,You lose.You will be forced to refund. Maybe it comes back to you 3 months later. I had that happen a few months ago. I am 6 weeks into another one and have not seen it yet.
