Fans of Burger King’s breakfast sandwiches are in for a treat– for one day only.

On Jan. 30, the fast food chain will offer customers a deal: croissant breakfast sandwiches for a penny.

The deal, reports Food & Wine, is in celebration of National Croissant Day.

Burger King’s croissant sandwiches (popularly known as the “croissan’wich”) are a staple on the restaurant’s breakfast menu. There are five iterations of the sandwich. The original packs a sausage patty with bacon, ham, or eggs with American cheese, served between, of course, a croissant. And then, there are the variations: just Egg & Cheese; or the Fully Loaded Croissan’wich, which is stacked with ham, bacon, sausage, eggs, and cheese.

Of course, with any deal, there’s a catch. Customers must be a member of the restaurant’s loyalty program. Patrons also need to place an order of at least $1 or more through the Burger King app or through the Burger King website during regular breakfast hours on Jan. 30.
