My hubby loves Firehouse Subs, though we don't go there much (stupid wheat allergy!). They do, however, have an awesome birthday offer for a free sub on your birthday. Previously, you had to sign up to get a certificate for a free sub on your birthday and now you just need to show your ID - one that has your birth date displayed on it (driver's license?) on your big day to get a free medium sub. Of course, you may want to sign up for their email promotion alerts because they will remind you a few days before your birthday to stop in for a visit to get your free sub. This information is current as of July1.
