FlipKart

Encountered with website few days back, UI looks great, shopping cart is really interactive & after reading lot of review finally ordered a book,"The Road by Cormac Mccarthy", that was in stock & expected time for delivery was 2-3 days, to my pleasant surprise book arrived in time & nicely packed & on top of that I got the big discount plus free shipping.I was bit afraid for on-line shopping but after this nice experience i find FlipKart as the best option for buying Books.
You get the best discounts,free shipping & best customer support from these guys as a result i have ordered the 2 new books 2 days back "Stay Hungry Stay Foolish by Rashmi Bansal" and "Missed IIT by Neeraj Chabia"
