 because it's about thriving, not just surviving Shake Shack is definitely known for its juicy burgers, fries and, of course, shakes. And, for a limited time, customers can scare up big savings on the Double ShackBurger at the popular restaurant.
The Double ShackBurger is made with two quarter-pound 100% Angus beef patties, American cheese, lettuce, tomato and ShackSauce, on a buttered and toasted potato bun.
From Oct. 22 to 31, 2025, Shake Shack is offering a buy-one-get-one FREE Double ShackBurger at participating locations — with promo code SPOOKY. (Be sure to use ALL CAPS, as that’s the only way the promo code will work.)
The offer is only valid for qualifying orders placed at a kiosk in-restaurant or for delivery or pick-up via the Shake Shack app or at shakeshack.com.
You must add at least two Double ShackBurgers to your cart prior to checkout. The discount excludes paid add-ons, including bacon, avocado and more.
Limit one FREE Double ShackBurger per order.
Shack Shack has 352 locations in 33 states.
