App is a hassle and it doesn't appear that subway cares. Tried to remove an item and kept getting errors. tried to clear my cart and kept getting errors. Tried to check out and got an error that my tip % was too high despite not having the option to leave a tip yet. used the buy one get one code and got surcharged an extra 2 dollars because my order wasn't expensive enough. So my free sub ended up costing almost 7 dollars with fees. deleted app and subway out of my life.
