They only gave flash sales and loot you. The maximum number of promo codes are not working. If you order for 500 rupees or 5000 rupees you have to pay 100 Rupees for delivery. If they gave some discount on any products they will take the discount from the delivery. The time of delivery is too much large.
The refund is not to good. My opinion is not to go to website and buy anything. And this time go and explore Paytm not Paytm Mall.
