I recently purchased an book from there site, what made me to choose this website for this purpose was It accepts payment through SBI debit card(which is quit useless over Internet)+ 17% discount with no shipping cost .So I order my book and got 2-4 days delivery promise time, which was quit amazing in itself. And most importantly they kept there promise of delivery time and book was delivered to my doorstep on 3rd day.
The only thing I dislike about them is that they updated the status of my book order on the 3rd day with details regarding the courier service so I can track my order, which could had be done a day earlier, due to no status update I even tried to contact them, but had got no response.
