Doesn't remember your login half the time. You have to know if you're doing delivery or carryout from the get go or you'll have to redo your whole order when you try to pay, and sometimes it doesn't take all the ingredients you choose so you have to double and triple check your order before you even place it. Some deals aren't available for your store, but it doesn't indicate which ones. App itself is slow and takes longer to choose and order than it would if you'd just call the store.
