McDonald's is giving rewards members free medium fries with a $1 purchase for National French Fry Day 2026. The offer runs through the McDonald's app and is limited to one per customer at participating locations.
National French Fry Day is being marked by fast food restaurants nationwide with deals that stretch from July 7 through July 16. For customers, the real question is not whether fries are on offer, but which app, rewards account, or minimum purchase unlocks them.
McDonald's and Five Guys app deals
McDonald's asks for a $1 purchase to unlock free medium fries, a low entry point that still requires a transaction. Five Guys sets a different bar: customers get one free Little Fry with the purchase of a burger, hot dog or sandwich, and they have to enter FRYDAY26 at checkout on the Five Guys app or website.
That structure matters because these promotions are not blanket giveaways. They are tied to a rewards account, a promo code, or a qualifying order, which means the deal reaches the customer only if the app step and purchase step are both completed.
Chick-fil-A One, Jack Pack and Sheetz
Chick-fil-A One members can get a free medium-sized waffle fries from July 7 through July 14 by playing Spot the Cows in the app, and the reward is limited to one medium waffle fries reward per person. Jack Pack rewards members can get a free order of fries of any size on July 10 with a $1 minimum purchase, limited to one use.
Sheetz is offering one free bag of fries from July 10 through July 16 with a $10 purchase through the app under the OFFERZ tab, limited to one per My Sheetz Rewardz member. Those terms make the holiday feel broader than it is: the offers run nationwide, but the usable pool is narrower because each chain sets its own rulebook.
Whataburger and July 12
Rewards members can get free fries of any size on July 10 with a $5 minimum purchase, and Whataburger rewards members can get free medium fries with no purchase necessary online or in the app. Customers can also get free cheese fries with any order by using CHEESY from July 10 through July 12.
For anyone trying to use the day efficiently, the practical move is simple: check the app or rewards account first, then match the purchase requirement to the offer before ordering. The dates overlap, but the fine print does the sorting.
