I used to be in the book business. We would constantly see students and other sellers try to pass off Indian editions as the regular edition, and charge full price.
When I was in college, I made the mistake of buying an Indian edition for a class, thinking it was the same. It had much less content and the problem sets were completely different. It ended up being unusable and I had to buy the regular edition.

I remember before this case, books used to have a clause in its first page that resell or distribution is not allowed. So according to the first-sale doctrine, that clause has no enforceability?
