Free medium sub on your birthday

Firehouse Rewards members get a free medium sub with any purchase around their birthday.

Conditions: Free to join. To qualify, you need a purchase over $1 linked to your Rewards account (by phone number) in the last 6 months; purchases within 7 days of your birthday don't count. Redeem with the purchase of any item the day before, the day of, or the day after your birthday. Use it online, in the app, or in the restaurant by giving or scanning the phone number on your account. Only at participating locations.
