National French Fry Day was July 11, but Wendy’s is keeping the party going.

The burger chain has coined the term “Fryday,” and will offer a free any-size container of French Fries with any purchase on Fridays for the rest of the year.

But there’s a catch: Customers can only get the deal by ordering through the Wendy’s app or website.

According to Men’s Journal, the offer excludes Topped Fries, Seasoned Potatoes and Fuego Fries.

What else is new at Wendy’s?

This past spring, Wendy’s introduced the Cajun Crunch Spicy Chicken Sandwich. The new sandwich, according to Food Republic, takes the chain’s spicy chicken fillet up a notch with Pepper-Jack cheese, Cajun crispy onions, and a spicy mustard sauce.

Wendy is also offering a fresh take on its classic Frosty with Frosty Swirls and Frosty Fusions. The new Frosty Swirls will allow patrons to add a sauce to a chocolate or vanilla Frosty. The Frosty Fusions will feature those same sauces, plus additional mix-ins to make for an even more delicious experience.
