Once again this year, Firehouse Subs will be collecting bottled water and exchanging it for FREE submarine sandwiches. Donate a 24 pack of bottled water and receive a free medium sub. The bottled water you donate will be given to local first responders and community groups. They will distribute it to those in need. It’s a win-win for everyone: they get donations, you get free food! Don’t miss the Firehouse Subs H2O for Heroes event.
