App unusable to purchase
Hit a bug where I can put things in shopping cart but the buttons to pay are peeking up from bottom of screen but not usable. Would help if you actually did real world user testing across phones rather than just using your own…
Bad
App does not list the same items as the website.
DER App Pretty Glitchy
I tried to order today, and the app kept trying to add package protection to my order only to indicate package protection is not available in my area. I left products in my app shopping cart because the app literally could not complete my order.
Very user friendly
The UI is simple and user friendly. You can navigate to products easily, and the purchase experience is pleasant.
