The last 3 books I’ve purchased from Amazon (UK) have been of questionable quality. The most recent was Designing Data–Intensive Applications (O’Reilly) and I’m still not sure if it’s print on demand, counterfeit- or just a reject. Roller marks, damaged pages, slightly off print. The returns process is inconvenient, one-offs are okay but on multiple purchases it’s fatiguing and so the book stays.
This isn’t specific to Amazon, I had the same issue with Waterstones in the UK (online)
I now just buy second hand (Abe, WOB) and hope for the best.
For sure, if both Amazon and the seller are doing things the way they are supposed to be. There is a small chance, however, if the OP either purchases from an unfaithful third party seller, or somehow inadvertently from a third party seller even though they purchased from Amazon.com, due to how inventory is mixed (Amazon kept doing this for years).
