Those who have been craving Wendy’s and wishing they could eat it on a pretzel bun are in luck because the fast-food chain is introducing a new menu item that will definitely delight—a Pretzel Bacon Pub Cheeseburger. To make the new treat even better, there is also a way to get it which means it won’t cost them a single penny extra.

According to a press release, the burger will be available from Friday, Sept. 4- Monday, Sept. 7 to Postmates customers who order more than $15 worth of food. If they enter code PRETZEL at checkout, then they will be able to try to Pretzel Bacon Pub Cheeseburger for free.

While the same deal won’t be available there, the sandwich can also be ordered via DoorDash, Grubhub and Uber Eats, as well as through mobile orders on the Wendy’s app and on Wendy’

The sandwich is going to be a part of the restaurant’s “Made to Crave” line, and those who prefer chicken can swap out the beef for the other protein. The original sandwich is set to include a quarter-pound beef patty, Muenster cheese, three strips of Applewood-smoked bacon, smoky honey mustard, warm beer cheese sauce, crispy fried onions and pickles.

“We love working with our Culinary Innovation team to deliver on emerging food trends and flavors that customers can’t get enough of,” Carl Loredo, Chief Marketing Officer for The Wendy’s Company, said in a statement. “Like we did with Spicy Nuggets, we’ve been watching and listening as customers have been craving for us to bring Pretzel back. We married the fervor for our former pretzel bun with the increased love for gastropub-inspired flavors an created a cheeseburger that is, in a word, unforgettable.”

The new burger comes just under one year from the chain’s rollout of a breakfast menu, which included items like a bacon sandwich, a honey butter chicken biscuit, a Breakfast Baconator and a Frosty-ccino coffee drink. That menu has since grown to further include a Maple Bacon Chicken Croissant, Sausage Gravy and Biscuits, a Sausage Egg and Cheese Burrito, Seasoned Potatoes and an Oatmeal Bar.
