I sold a boxed set, audiobook on CD, and shipped them to the buyer and got the money no problem. She just sent me a message saying she can't play them on any CD players she has, and wants me to refund her (my auction stated no refunds) and pay for her to ship back the CDs. I want the money, don't want the CDs, but I don't want trouble with eBay or PayPal. I know the discs work because I've played them on a CD player I own and I uploaded the discs onto my laptop. Thanks for the help! What is my best course of action? What is likely to happen if she files a complaint to eBay?
