Hello My name is sachin,
Paytm is a good website but I like most paytm app its so simple and use full.
paytm in many offers and contest available.
paytm website and app in you can buy many products but if you have some time to search google some products you can see some products low price in some other websites so I think paytm is not good website for shopping but if you pay money to other site then paytm is best app or site.
paytm help centers is so nice. I recommend for pay any but not shopping in paytm sale.
Thank you for read:)
