Shake Shack is shaking up the end of the year with a juicy deal for burger lovers. The chain’s burgers are made with a custom 100% Angus beef blend, never frozen, no hormones or antibiotics ever, humanely raised and grazed in the U.S. And its signature burger, the ShackBurger, is a cheeseburger with lettuce, tomato and ShackSauce.
From December 26 to January 2, Shake Shack is offering a buy-one-get-one FREE single ShackBurger at participating locations — with promo code THANKYOU21. The offer is only valid for purchases made on the Shack Shake app or at shakeshack.com for pick-up or delivery. Limit one time use per account for a maximum savings of up to $6.39.
You must add at least two (2) single ShackBurgers to your cart prior to checkout. The discount excludes paid add-ons, such as bacon, avocado, shallots, cherry peppers and gluten free bun.
And, for a limited time, get a FREE shake for every $25 purchased in gift cards — click here.
There are 7 locations in Colorado — Boulder, Denver (4), Highlands Ranch and Lone Tree. (Note: The location at DIA is not participating in the BOGO offer.)
