I sold a collector book on eBay last week. The book was in perfect condition with the shrink wrap. I didn't not notice any damage when I have it. I am pretty sure it was in perfect condition. I also package it very well with tissue paper wrap around it. The buyer contacted me today saying the book's top conner was damaged. But she didn't say want she want me to do yet. I dont know what I should do. I specific all sales are final in my listing, and I did buy insurance for the shipping. Should I file a claim with USPS? The worst case would be my book was in good shape, but the buyer now switch to a damaged one and want to return it. What can I do if this is the case. p.s. in my eBay listing, I have picture of the book showing it was in good condition. Please help!!!
