Horrible! I've reinstalled the app a multitude of times on copious amounts of occasions. It has only ever worked for me once and in that occurrence, it first completely ate my gift card amount and then wouldn't return it or credit me for it for hours even after I placed my first and only initial order. Since then I have been unable to use it due to an error message that pops up every time I try to please another order. And moreover I'm unable to use my remaining balance. Help vehemently upset.
