After launching during the 2026 MLB season, Firehouse Subs' "Extra Innings, Extra Subs" campaign will continue in the Postseason. Throughout the playoffs fans can get free subs depending on extra-innings action this October.
If any MLB Postseason game goes into extra innings, Firehouse Subs rewards members can buy one medium sub and get a second medium sub for free with the code "POST" on the Firehouse Subs site or app.
Full terms and conditions apply, and the deal expires one day after each extra innings game is played. So keep an eye on bonus baseball this October and leave room for an extra medium sub
