My wife and I got through college ordering used textbooks from India for literally pennies on the dollar. I see some mentions that Indian textbooks are sub-par quality-- not so in our experience. We'd have the same hardcover books as our classmates, only the jacket would be a different color and labeled the "international edition." They'd always have page-sized EULAs threatening brimstone and firing squads if the books were used outside of select Indian universities so there's clearly some generous licensing going on. Since the same goes for Indian pharmaceuticals (pennies on the dollar compared to retail price in the US), I doubt they can get away with extorting Indian students to the extent they can American students.
