Paytm is very good site for new products and there value. And cashback is very good option and with that cashback we can do anything
But do check all the other sites when you are about to buy something on paytm. Cause I have found that some products are actually cheaper on amazon or flipkart
And main thing is delivery is slightly late when we compaire paytm with other sites ( PDODUCTS NEED 1 WEEK TO COME TO YOU).But for recharge this site just rocks. You get cashback on every recharge use( GRAB4) this promocode and you will get min. 4% cashback. Other wise site works good
