Payumoney is a payment gateway. through which we can do our payments while purchasing online.
When the payment option comes when you are purchasing from the online shopping soite, which have tie up with Payumoney, then select the option payment from payumoney. Then just login to payumoney and do the payment.
And the benefit of it is you will get discount on it.
Discount is purely depend on Payumoney and the tie up company.
Snapdeal.com, freechare.in, bookmyshow.com, goibibo, foodpanda, are some of the companies, which have tie up with Payumoney.
So you will get discounts on this website.
I always book my movie tickets on bookmyshow, with payumoney gateway. and I get discount everytime.
