On December 18, for one day only, you'll receive a free Hardee's burger in-store when you wear your ugly Christmas sweater and purchase a large drink.
You'll receive your choice of a Famous Star with Cheese Burger or Western Bacon Cheeseburger for free, but make sure to also say "Ugly Christmas Sweater" while placing your large drink order.
You must visit your local Hardee's in person to redeem this limited time only deal.
