Shake Shack is shaking up fall nights with a sweet deal. Enjoy a cool autumn afternoon with a cool treat — even better with a friend or family member.
And, of course, the popular restaurant is known for its delicious shakes, in addition to the juicy burgers and crispy crinkle fries on its menu.

From Sept. 12 to Nov. 30, 2023, Shake Shack is sweetening fall afternoons with a buy-one-get-one FREE shake special at participating locations — including non-dairy, limited-time and classic flavors.
The order must be placed on the Shake Shack app, online at shakeshack.com or at a kiosk in-Shack. (The offer excludes locations at airports, stadiums, arenas, travel plazas and museums.)
The discount excludes paid add-ons, such as whipped cream and malt. In addition, regional-specific shakes do not qualify for the BOGO special.
Here’s how to get the deal:
1. Add two shakes (any flavor, any size) to your order.
2. Make sure your order is scheduled between 2 p.m. and 5 p.m.
3. Enter promo code FAVESHAKE at checkout.
4. Pick-up your shakes and enjoy!
The offer only valid for orders scheduled between 2 p.m. and 5 p.m.
The deal is not valid for drive-thru purchases, delivery or curbside pick-up or for orders made through third-party delivery services.
Limit one time use per order — with a maximum savings of up to $6.59.
