There are now a couple of stores brewing around from where you can buy the Raspberry Pi online in India. Many of these stores also stock getting started kits and other accessories.
Since, I’m based out of Hyderabad, I’d like to recommend PotentialLabs for buying Raspberry Pi if you’re based in Hyderabad, Telangana/Andhra Pradesh. Buy from my MakerStore at http://potentiallabs.com/cart. We ship same day or you can also pick up from our Brick and Mortar store.
Other prominent stores where I have purchased include:
Simple Labs – http://simplelabs.co.in
Explore Labs – http://www.explorelabs.com
MG Super Labs – http://www.mgsuperlabs.co.in/estore/
There are tonnes of other stores, but I’ve had a nice experience with the above ones.
