Aweful. App is broken half the time and doesn't work at all, the other half the time it adds an entire previous order to your cart right before you check out and makes you buy twice as much as you wanted to. Then you find out there is no cancel order option for either you, or the store and you have to spend an hour on hold waiting for customer support so you can get your money back. But wait, there's more! When they refund you, it takes 14 days for the money to go back to your card. Good luck!
