So I sold some printer ink for about $30 plus shipping to a buyer in Canada (I'm in the US). I shipped it first class, which is what the buyer paid for (I did have a priority option). It left one of the local sort facilities, but there is nothing that shows up from the customs form number after that. Auction ended on March 28th and I mailed it the 29th. The buyer contacted me on 5.21 and says he didn't get it. I asked at my PO and they don't have any additional info, I advised him to contact his delivery person and neighbors, and he says none of them know anything. He is asking for a refund since I told him I am unable to offer replacement since I'm not a store that regularly sells the same thing.
It is well past the Paypal claim period, but he can still leave negative feedback for another month or so. I have 100% positive feedback with 872 rated transactions. My inclination is to either ignore him at this point or just tell him 'no' as nicely as I can. Feels sort of like feedback extortion to me, since he really should have filed a claim a month ago during the paypal period, though he has never said anything about feedback.
What would you do?
