Paytm is Indias best online site for mobile recharge. I always do my recharge for my family through paytm via cashkaro. I will login cashkaro and check offers in it for paytm so that I will get both cashkaro cash back( upto 3 percentage normally) .
Depending upon current offers, paytm offers upto 65 rs cash back for payments above 500. Sometimes it offers upto 6-8% cashback.so if you use paytm and cashkaro together for all your recharges you will be saving a descent amount of money .
