If you have a registered Burger King account, you can score a free medium order of fries through to February 28, 2022 at participating Burger King locations.
With this one-time use promotion, you can claim free fries when you purchase a $1+ order using either the Burger King website or the BK App while logged into your account. You'll also need to add your in-app or online coupon before placing your order.
This Burger King offer is valid with both in-store pickup and order ahead purchases, but cannot be combined with delivery orders.
