I agree that the ambiguity between 'like-new' and actually new, but mildly shopworn would make it hard to tell a material difference between the two occurrences, however this:
> nobody complains their book was "fake" with a 95% discount to keep them quiet
This is conflating dishonest substitution of counterfeit goods with consensual purchase of a lower-quality product. If I'm not explicitly purchasing the 'international' version of a book, I would consider myself harmed and defrauded if its materials and construction are not up to expected [North-American / Western / ?] standards.
The user explicitly consenting to purchasing a knock-off is another thing entirely from having the seller 'fulfill' a purchase for a genuine item with the same knock-off.
