Papa John’s has teamed up with Major League Baseball (MLB) to offer a new Papa Slam deal. Here’s how it works. Any time a player hits a grand slam during the 2016 MLB season, Papa John’s will give you a 40% discount on any pizza at regular menu price the following day (online orders only). Use the promo code PAPASLAM.
So far, Papa John’s has been posting grand slam updates on its Facebook page, so you may want to check that before you order.
