This app is actually not worth one star at all. I joined in good faith and bought one item which was not delivered at all. No message, no nothing from the seller.
I then got a message from the App admin saying I would get my money back in five days.
With that confidence I bought another item. That was ten days ago. Again there was no attempt to deliver and this time, there is no attempt to refund the money either.
If you see this review, please do not use this app as you will lose your money and your time.
