I have been using PayTm for a long time now and it has never disappointed me. The website is smooth and loads fat, the interface is user friendly and I never got confused. I do all my recharges, including mobile.
DTH, data card and megro card recharges from PayTm and it is so useful. I have not done shopping from the website but I will soon try that too as the offers that they offer are nice and attractive so looking forward to that. Will tell you about that too.
