The buy-one-get-one deal is valid for eat-in or take-out, but not at Shake Shack locations in airports or sports stadiums or ballparks. (In NYC, Shake Shack has locations including at LaGuardia Airport and Yankee Stadium.)

To take advantage of the BOGO offer, simply grab a ShackBurger in the brand’s app or online with promo code THANKYOU21 to qualify for a second ShackBurger for free, for yourself or for a friend.  Split an order of fries and add a drink for each of you for a full meal.

You must be signed into your Shake Shack account to apply the discount.  So if you don’t have one, this would be a good time to open one.  It’s free to join.

Shake Shack doesn’t offer many deals. 

Earlier in 2021, Shake Shack offered FREE fries to vaccinated customers.

In 2017, Shake Shack offered FREE burgers for the introduction of its app.

In 216, Shake Shack offered a FREE meal for holders of the American Express Delta SkyMiles card.

So Shake Shack deals are few and far between.  Take advantage of this one, since we don’t know when the next one will be.
