So as many here knows I recently bought then flipped a gen omega speed master. I made a few bucks and shipped the watch to the buyer with tracking, insurance and signature confirmation. The buyer insisted that I ship the watch to an address that the post office could not find in there database. So I figured maybe it's an apartment or something. I shipped it overnight and the next day, nobody was available to sign for the package. Then it appears the watch has been attempted to be delivered four times already with tomorrow possibly being the last time before I guess it gets sent back to me. What do I do in this position? I already called PayPal and they said I did everything right and I shouldn't worry. The item was paid for and I withdrew the funds from PayPal already. I'm just worried that he was going to try and scam me but being that I have signature confirmation and insurance, maybe now he will try to fight me saying it was not as described/broken or that he didn't get it. Anybody have any advice? Prior similar circumstance?
