I have been using paytm mall app for 3-4 months. Many of the items you see are costing reasonable price have a separate shipping charge too, adding this to the product cost makes the total amount more than what has been offered by other sites such as Amazon. I saw lancer shoes costing 450 with offer but on checkout a delivery charge of 195 was added so the total cost was more than what has been offered by Amazon without any offer.
