Strange to say, I ordered a classic paperback science fiction book from Amazon. Shopping image was of a standard pocket book, used. (Imagine del Ray publishing from the 70's.) What arrived, was a Xerox? copied book with a water mark, on American standard 81/2 x11" paper. It was almost unreadable because of water mark. It wasn't a paper back. It wasn't original publisher format in any way. This has happened twice now, in completely different genres. I am dubious of buying any books from Amazon now. Powell's Books instead.
