Immediately after placing an order, I realized I had forgotten to put in my coupon, so I tried to cancel the order. There is no option. I was at the store already, so I asked the staff. They also have no way to cancel it. So I was out $1.40. The previous time I used then app, it preselected the veggies, so when I chose them I ended up deselecting them and got only a piece of bread with a few olives and peppers on it. There are other sandwich places that let you cancel and are easier to use.
