The app works about half the time. The last time I used it I was over charged & one sub was right. The other was totally wrong. Most of the time I think you're better off just going into the store. Update: this app is terrible & it never works. I live in spitting distance from a Subway, I can never get it to work, we NEVER get the deals,or promos. Full price every single time. I've reached out to them at least twice, nothing. I'm done, I will go out of my way to avoid their sub-par sandwiches.
