I would definitely contact them and explain the problem. I’ve found that Amazon frequently throws one book into a much larger box with a few air pillows floating around inside, and the DJs get wrinkled, corners bumped, etc. They’ll definitely let you return it for free if it was a new book, but they might even replace it without asking you to return it.

If you buy from a third party seller (Marketplace) you should still be able to do a free return and be refunded if you return within 30 days. But if I’m doing that, I always check to make sure the seller does free returns.
