I’ve said it before and I’ll say it again, this situation and the others people referenced in the thread are the reason that I both do not buy used, and also do not sell to private parties. On the rare occasion I sell gear, I walk in my local GC and walk out with a pocketful of bills and a smile 20 min later, the difference between what they give me and what I could’ve made in a private sale I consider a convenience fee I pay to completely avoid these types of situations.
