From May 1 to June 1, 2025, Shake Shack is offering a different single burger for FREE each week with a $10 minimum purchase at participating locations. The offer excludes all paid add-ons such as extra avocado or bacon.
Here’s what burger is available each week:
May 1 to 11 – SmokeShack
May 12 to 18 – Bacon Cheeseburger
May 19 to 25 – Avocado Bacon Burger
May 26 to June 1 – ShackBurger
The offer is only valid for purchases placed at a kiosk in-restaurant or for delivery or pick-up via the Shake Shack app or at shakeshack.com. Use promo code BURGERMONTH at checkout. (Note: Promo code must be entered in ALL CAPS.)
Limit one offer per order, with a maximum savings equal to the price of each week’s promotional burger (from $8.49 to $11.49). If you have a large order, consider breaking it up into separate transactions for the best savings.
You must add at least $10 worth of food and/or drinks to your order, excluding the cost of the complimentary burger. (Gift card purchases are also excluded.)
