Sold a baseball jersey to a guy in North Carolina a couple weeks ago. Sent to the confirmed address on his PayPal account. Jersey came back today from post office marked "Insufficient Address," and I had to pay the return shipping because I mailed it Standard. Coincidentally, before I had a chance to contact him, he sends a request today for a refund via PayPal. I send him a message via eBay saying no-can-do--I've already lost money on the deal due to return shipping charges (this wasn't a high margin transaction, but I had, at least, come out a couple bucks ahead). After I explain it to him, I notice a message he had sent after winning the auction that I had not previously read. In the message, he provides an apartment number that is not on his PayPal account. Woulda, coulda, shoulda, but I hadn't noticed that message until just now, and I know better than to ship to any address that's not on the PP account. Had I noticed the message, I would have contacted him and told him to get the apartment number on his PP address and I would ship then, but too late now.
I'm guessing this guy, who is brand new to eBay, is gonna squawk--his messages have "that tone." Any guesses on how this will end?
