I love paytm, because I got many product from paytm at lowest price. Paytm only available site which provide cashback for every products.
I take part in 100% cashback offer and got many product at 0 Rs.
Main disadvantage of paytm is its Website load time, which causes problem to find exact product.
But I like Paytm for doing recharge/bill payment and shopping.
Another great aspect of paytm is its Paytm wallet, which uses in many other websites.
