To successfully redeem a reward with your order, please add the menu item you wish to redeem to your order as an individual item, rather than as part of a meal. When redeeming a reward via the Chick-fil-A App, switch the ‘Redeem Rewards?’ toggle to ‘On’ and the redeemed menu item will appear with a ‘FREE’ icon in your mobile order cart before continuing with the order.
You cannot substitute a reward for a different menu item, but you can modify your reward with a special request such as extra pickles.
