I have purchased about 10 odd books from flipkart for the last few months and am generally happy with the deals and the service I am getting from them.
Books are cheaper than stores like Landmark or odessey, books are delivered at your door -free of cost and by and large hassle free transactions.
Cash on delivery means no need to put the credit card details on the net - which is a relief. Today even though we book air tickets and so many things using credit card online - always there’s a nagging fear of abuse by some malware. So cash on delivery is a killer business model.
I am very satisfied with flipkart so far and happily recommend them to others
