Free burgers & Nashville hots at Shack Shack this week

Shake Shack has launched two secret offers to Shack insiders, but you’ll have to act fast if you want a free burger, chicken sandwich or Shack shake.

Standalone Shack locations (so not airports, kiosks or arena stores) are all offering BOGOs this week only, but you have to order through the Shake phone app or website to get the deal. The Buy One Get One Free deal is valid on the ShackBurger, SmokeShack, Hamburger, Cheeseburger, Hot Chick’n, Chick’n Shack, and ‘Shroom Burger (but not doubles, Shack Stacks, or regional burgers). Enter the code “Thankyou” at checkout to score the BOGO deal. Want something not BOGOd? Enter “shack2020” instead to grab $5 off your purchase (no minimum required). The deals are valid until 1/3/2021.

Fine print: at participating Shake Shack locations on the Shack App and on order.shakeshack.com (excluding airports, stadiums and ballparks). One time use per account. Max savings of $7.89. Must add two qualifying burgers or chicken sandwiches to cart prior to checkout. One-time use per account.
