I have not had any issues with purchasing textbooks from Amazon in the past few years, whether it is new, used or fulfilled by Amazon.
Just received 3 new textbooks today (Amazon Prime), and one (3rd party but fulfilled by Amazon) came with the 3rd page folded different ways with creases, and the next few pages are a little curvy. Such minor issue I say to myself, not justified to request for replacement. But it does bother me a little.
Obviously it is not damaged, and it sure won’t affect studying!
Would you ask for a replacement?
