Firehouse Subs is a smaller sandwich shop with over 730 stores. I ate there last week and I was impressed. The cost of the subs run around $5-6. Good news is they have a Military Discount! They offer 15% off everything!
I contacted their support team yesterday and asked if this was a national discount. They said no. They said it is up to the individual owner of the store. Hopefully your local owner is pro military discounts 🙂
