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.
