Was trying to use a promotion advertised to me through a notification, got the order in finely, then the restaurant needed to edit something due to not having a certain ingredient in stock, app tabbed out of the menu and just completely erased the item from the order (Leaving literally just a couple drinks), so I had to cancel it due to it being around $15 for just that, then I got charged a cancelation fee and the rep basically told me nothing could be done. Wonderful app. Stick to Doordash.
