Greetings: In my @2000-item selling history dating back 18 years on eBay, I have never received anything but positive feedback: I'm not out to screw anyone over. My light selling these days is limited to personal items. Recently sold an American-made acoustic guitar that my dad bought new in the early/mid 1980s with the idea that he would learn to play. He gave it up--literally--in a matter of days, and the guitar has been moved from closet to closet for 30+ years. Strings were changed once over the guitar's lifetime. I took the best iPhone photos I could at various angles showing how sparkling clean this guitar is. Conservatively, it's in 9.8 out of 10 condition. I included the measurement from the 12th fret to the strings. The guitar sold with 1 bid at $700 to someone cross-country; shipping via FedEx Ground was $95. It's the original factory case with no wiggle room, but I packed well around the headshell and the neck, with padding between the strings and the fretboard. I shipped it inside a heavy-duty acoustic guitar box I picked up from Guitar Center. I followed the tracking online, and I saw that the guy received it this Monday and he promptly left me positive feedback. Great, I thought; another eBay success story. Not so fast. I got a notification for a return request today. Ugh. In his request, he cited that there is light swirling/haziness in one area due to polishing; that there are scratches on the back of the neck around the 12th fret; that he sees preliminary signs of the mahogany top separating, and that the neck is slightly bowing back. I would guess by the fact that he did leave me positive feedback that this isn't an out-and-out scam attempt for extra money back, and I'm not sure how to proceed. Is eBay's official policy these days that the buyer has to return the item at his cost, at which point I am to refund the purchase price plus his original shipping? For awhile in the mid-'00s I sold on eBay as a source of income, but as I mentioned, I'm out of the loop these days on policy. I realize that it's hard to buy something like a guitar sight-unseen, though I know this is a nice guitar with none of the trumped-up issues he is stating. Is it in my best interest to offer $100 back to close the deal? Input & advice welcomed. Thank you.
