With more than 450 Firehouse Subs restaurants in 29 states, Firehouse Subs is doing a lot of things right. People come back when they’re treated well, and fed even better. Turns out, people absolutely LOVE the same things we do – the best meats, cheeses, and toppings. People come back again and again because, unlike other sub places, Firehouse Subs steams their meats and cheeses, releasing a rush of flavors, then stuff a serving that’s way over code on one of the toasted private recipe sub rolls. It’s a winning combination that satisfies ravenous appetites and the value conscious alike. Sign up for the Firehouse Subs newsletter and they will keep you satisfied with information about special promos, offers, and other news from Firehouse Subs. Plus, a few days before your birthday they’ll email you a reminder to come in on your big day for your free medium celebratory sub. Sign up. As a thank-you, you’ll receive an online certificate for a free large drink or bottled beverage with the purchase of any sub. View other printable coupons and deals.
