Be very careful when using this app. They try to very sneaky and get as much money out of people as possible without them knowing. For example, if you go to place your order and add tip, but then go back to add something else, if you add that tip again, you will be charged twice for that tip. So if you select 30% tip, then go back to add more items, and then select 30% tip again, they will actually charge you 60%!!! So be very very careful when using this app.
