Unlike other site paytm offers cashback on almost every product which is this great stretagy.
Paytm has taken the position freexharge earlier I use free for bill payment but I my using paytm ehy?
Paytm offer more cashback and than freecharge plus paytm can used on site like bookmyshow, foodpanda, uber cabs etc.
Paytm will become no1 company for billpayment and wallet services.
I would recommend this site.
