Surely if you measure cheap by what starts at 350 rupees. A lot of things get cheaper.
You keep changing stance - most foreign books are not cheap(they are), technical books aren't the only books(no they are not; fiction is cheaper, non-fiction is a bit higher), and lastly 350 isn't cheap. Doesn't my very first comment in this thread has 236 termed as "quite low"? If your basic objection is 350 isn't cheap for most books, why bother with the needless arguments about foreign books and novels.
