Firehouse Subs invites guests to help local first responders to beat the heat during the 6th annual H2O for Heroes bottled water collection drive on Saturday, August 5, at all Firehouse Subs locations in Gulf Breeze. Each guest will receive a medium sub when they donate an unopened 24-pack of bottled water. (Limit one medium sub per person, per case of unopened 24-pack bottled water.) The donated water will be distributed to local fire departments, first responder agencies and community centers aiding children, the elderly and those in need of water during the scorching summer months when dehydration and other heat-related illnesses are most threatening.
