Paytm is very handy esp the paytm app which makes your life very easy esp when it comes to mobile recharge dth recharge movie tickets etc. The biggest advantage is the daily discount coupon. It also facilitates the sending and receiving of money. Paytm also has started selling of different products in different categories. The one I would suggest that paytm should start supporting railway reservations also it would make paytm onestop app for various day to day shopping.
