Terrible usability!

This app is THE WORST! I downloaded it to manage my wedding registry and am unable to add multiple quantities of the same item. Also I have tried making a purchase through the app and nothing happens when I try to add a coupon to my order. There are various buttons throughout the app that are not clickable, and its enough to drive any normal person to the brink of insanity. THE WORST APP!!!!
