I am not satisfied with the offer codes (coupon code) of this app. Because if you applied any discount code for buy something, and somehow your transaction faliled then you cant use that discount offer. Because if you retry to buy that product and apply code then app show a message " The coupon code has been already availed by you." So we cant use that again.And there is always a glitch about transaction in this app. You cant make online payment at first try. I am so dissapointed.
