What's different in the "Indian Edition" of the TOEFL Books?

Hey folks, I was browsing amazon.in to look for TOEFL Official Practice Test book, only to find that there are 2 types of books: The regular (Rs. 2700) version and the "Indian/To be sold in India" books (Rs. 899).

Does anyone know the difference between the two editions?? I can't deduce from the reviews because of the lack of reviews in the Amazon marketplace.
