Paytm is a big online shopping app and it is useful for saving or keep money in paytm.But with there is necessary to make small change in paytm mall that it is not to wide in some areas, so other reason is that sometime anyone one when it want to buy product there is a person confused to purchase the product with promocodes.Sometimes there a person want to remove the promocode he is unable to change it.because on that time he ordered its product.So I wish to make small changes in paytm mall online shopping app.
