Paytm is very good application and come with nany more features like mobile /D2H/Data card and it also come with online shopping feature with maximum cash back service.
I used it from last 3 years for mobile recharge and online shopping becouse it give us cash back and I got upto 70% cash back on my first purchage of my whey protien and I got it genuine product.
I was shoked when I got my protien next day to shippment and a original product delivered.I suggested to all people who want good deals and cash back offer then go for paytm.com or paytm mobile app.
