Editor's Pick: Firehouse Subs has released a batch of coupons in the app. You can get a second medium or large submarine sandwich at half price when you buy one. Other offers include $4 off orders of $20 or more, and 30% off orders of $30 or more. If you're a regular customer, check the "Offers" tab in the app to see which coupons are unlocked for your account. Note that the brisket sandwich is excluded from this promotion, and coupons cannot be combined with other discounts. The offer is valid until May 25th next year. If you're used to ordering via the app, activate it now and save it for later.
