To score the deal, simply buy any Frosty (size small or larger) in the app, and you can redeem an order of any size fries for free.

Wendy’s Frosty menu currently includes the seasonal Pumpkin Spice Frosty and Classic Chocolate Frosty.

The deal can be found in the “Offers” section in the app Rewards Store or on the brand’s website. From there, simply apply the deal to your mobile/web order or use the offer in-restaurant by adding to your digital rewards card before scanning at the counter or drive-thru.

Wendy’s decided to drop today’s FRYday deal in honor of Taylor Swift’s October 27 re-release of her pop album 1989.
