For mobile and dth recharges, PayTM works fine.! There are some discount coupons, which they give, which are attractive enough to get some good benefits. For product purchases, I am not sure how they deliver and are there any replacement or product warranties! also, not sure of the delivery time of the products, which I felt for some as more than usual time, from their peers.! Have not tried out their money transfer and other useful services, provided by them.!
