Tip for online book shoppers in India: Compare prices at Iglooo.in and isbn.net.in before buying. I got The God Delusion from landmarkonnet for Rs. 171 (After 10% discount), which is available for as high as 325 at some other sites. Don’t remember when I last bought a book from Crossword or a bookstore.
Also whenever you buy something online always search for discount coupon codes for that site. I searched for a coupon for landmarkonnet and got 10% discount. :) RetailMeNot is the site to find coupons and Google is always there.
