Firehouse Subs has launched an app that allows customers to earn food rewards on their purchases, order from Firehouse, find locations, and more. The app is available for all US locations, except Puerto Rico. Customers can earn one point for every $0.01 spent at Firehouse Subs, and save up their points to redeem free food rewards for subs, upgrades, and more. The app also offers a free large drink for signing up and a free medium sub on the customer's birthday. <br/><br/>To use the app, customers need to sign up for a Firehouse Rewards account, enter their phone number at the register every time they visit Firehouse Subs, or order via the app to automatically earn points. When customers have enough points for a reward, it will turn yellow. They can then tap on the reward they want to activate it, and enter their phone number next time they order to redeem the reward, or redeem when checking out in the app. Points earned are based on the pre-tax post-discount amount spent. <br/><br/>Rewards cannot be combined with other rewards, discounts, or offers.
