I used payumoney when I felt difficulty in paying for book in amazon.the benefit of it is you will get discount on it. Discount is purely dependent on PayU and the tie up company.Snapdeal.com, freecharge.in, bookmyshow.com, goibibo, foodpanda, are some of the companies, which have tie up with Payu.
I always book my movie tickets with payU and I get discount always.I recommend using payumoney wherever possible. Using payumoney is a better option than any other online payment site such as paytm. If you want to make safe payment of your bills go for payumoney. . if you want to purchase anything just give payumoney a try you will definitely steal your heart.
