Paytm is good only if you use it for recharges and bill payment, but please don’t use it to buy products as there is a high chances that they will cheat you.
At first I want to tell you something , sometimes when you click the product to buy, I don’t know how paytm site is redirected to AliExpress.com.second and then you won’t be able to place an order. Second and important, I ordered 2 puma slippers from paytm and they were fake, when I asked to replace.
I didn’t receive any reply from there side. But after repeatedly reminder and mails after one month, they said your location in not a serviceable area.
