Hex Girl review for ADU: Automatic Discounts

Paid $50 just to unlock the app to find out it does not allow me to do what it literally advertises. This app claims you can create discounts based on the URL which the customer comes from (I'm trying to give a discount to customers with a .edu email). I upgraded twice and even on the advance plan there is absolutely no option for this. Not user friendly and quite frankly a waste of money since the app description misleads you to believe the app can do more than it says. I literally paid to unlock a feature that doesn't even exist. Wish I could be refunded.
