I have a better idea. Which service did they use? USPS, UPS or FedEx? Which company did they damage the packages mostly? I think UPS damages mostly. At one point, the box was torn open then was taped after I picked it up at UPS hub few years ago. I opened and checked one book - Hulk #181 CGC 7.5. It survived. It's rare to see the damaged boxes were delivered by USPS or FedEx to my home.
FedEx will deliver my books to my home this Monday. See what happens.
I work for UPS and have seen people are roughing on the packages. Right now, it is in a high seasonal toward Xmas. My hourly schedule is now expanding due to the high volume. I expected to see more damaged boxes.
Maybe, 25 books in one package is damage-prone. Mine is only 6 books. Wait and see. I will tell you when I receive my books.
