I bought a chess book from a third party (The Book Depository) via Amazon last week. The price, about 50% below Amazon's own copy, seemed a bargain, but when the book arrived it was clear why:
The book wasn't from the publisher's standard print run, but was instead an inferior 'print on demand' copy (an individual book printed to order). The paper was thinner, the cover less stable and the print is not as high quality.
I don't mind this too much because of the cost saving, but was annoyed that the advertisement suggested it was the standard version and made no mention of it being a 'print on demand' copy.
Have you encountered 'print on demand' chess publishing?
