I bought a book from a very large comic website that most here probably know. It was a flash 123 and this was early in my comic collecting days. I sent it to cgc and it came back restored with slight amateur color touch. Not exactly an apple-to-apples comparison with the buyer here not properly inspecting their book, but in my case, this reputable seller offered a full refund on the restored book as they sold it to me as unrestored. I ate the CGC and shipping costs, which some have suggested here is what they consider a fair outcome. I felt this was a fair enough outcome for me, and feel the seller was as accommodating as they could be. I respected their customer service as they took ownership for not catching the restoration. I think them paying the cgc fees is a tough ask from a buyer’s perspective. I would’ve loved if they accommodated, but they sold me a raw book and I decided to get it graded. Not sure what would have been the “morally right” outcome on the cgc costs, but I was just happy to get out of the book cost.
