Burger King extends their “free fry with any purchase” BK App deal through the end of 2023 (December 31, 2023).
Under the terms of the deal, you can get a free any-sized order of French fries with any purchase using the BK App. It can be used once a week (i.e. it refreshes weekly).
The deal was originally slated to end in 2022 but was extended through June 30, 2023 and is now being extended again.
