I recently order 2 science fiction books from Book Adda, and the thing I liked the most is the customer service and personal approach they offered.
First of all the books are pretty cheap as compared to flipkart, for eg ordered a book for Rs 38(now can you beat that)
Also the customer service was very nice enough to follow about the books and they suggested about some more titles which I would love in the fiction section
i would say that these guys are nice ones and the good thing is that they focus only on books. Which means that once you buy a book you don’t start getting promotional mails about buying a TV, phone etc etc.
