McDonald's is giving away free medium orders of its famous fries every Friday until the end of the year when you make any purchase.
This "Free Fries Friday" promotion runs from October 27 to December 29.
To grab this offer, download the McDonald's app and create an account.
On Fridays, the app will prompt you to enjoy the deal. You'll find the free medium fries in the app's deals section.
Note that it's one per day, and your purchase should be at least $1. If you use the free fries deal, you can't use other app deals that day.
McDonald's has been generous with freebies lately, offering free fries in July for National French Fry Day and free six-piece McNuggets in January to celebrate the item's 40th anniversary.
Last month, they sold double cheeseburgers for just 50 cents on National Cheeseburger Day.
