How to Claim
- The Deal: Get one FREE burger with any purchase of $10 or more (excluding the price of the free burger, taxes, and fees).
- The Promo Code: Use code FREEBURGER at checkout.
- Note: The code must be entered in ALL CAPS.
- Where to Order: This deal is valid exclusively through the Shack App, ShakeShack.com, or at an in-Shack kiosk.
- Exclusions: This offer is not valid for drive-thru orders or third-party delivery services like DoorDash or Uber Eats. It also excludes locations in airports, stadiums, and rest areas.
- The Limit: There is a limit of one free burger per order.
Pro-Tips for Maximizing Value
- The $10 Strategy: To hit the $10 minimum without buying another burger, try ordering a Hand-Spun Shake and a side of Cheese Fries. This usually clears the $10 threshold perfectly.
- App Rewards: Make sure you are signed into your Shack account. Buying your sides through the app not only gets you the free burger but also earns you points toward future "Shack rewards".
- Kiosk Shortcut: If you are already at the restaurant, don't wait in the regular line. Head straight to the digital kiosk, enter the code FREEBURGER, and your discount will apply immediately before you pay.
