Flipkart is really good for buying books. There you can find very good discount than book stores some times its upto 50 to 60% off on books or ( you can also called it a great sale on books) . Delivery period is also amazing 2 days is maximum time which is taken by Flipkart which is really reasonable in my sence and some times there is off shoping upto 500 no shiping charged will charge.
