Craving a juicy burger or a crispy chicken sandwich? If you have a Shake Shack nearby, you are in luck! There are two overlapping offers this month where you can score some cheap burgers!
Deal 1: Free Single ShackBurger With BBQ Purchase
To celebrate the launch of their new limited-time summer menu, Shake Shack is giving away a completely FREE Single ShackBurger (regularly $7.99!) when you buy any qualifying Smoky BBQ entree. This promotion runs from now through June 17th, 2026.
How to score it: Add at least one Single ShackBurger AND one qualifying Smoky BBQ sandwich or burger to your digital cart. At checkout, apply the promo code BONUSBURGER in all caps to drop the price of the ShackBurger to $0!
Qualifying BBQ Entrees Include:
- BBQ Boneless Baby Back Rib Sandwich
- Smoky Classic BBQ Burger
- Smoky Classic Chicken Sandwich
Deal 2: Free Chicken Shack Sundays Are Back!
If you prefer chicken over beef, make sure to clear your schedule every single weekend. Every Sunday through June 28th, 2026, you can grab a FREE Chicken Shack Sandwich or Chicken Shack Lettuce Wrap with any order of $10 or more!
How to score it: Build your cart with at least $10 worth of food or beverages (the cost of the chicken sandwich doesn’t count toward the minimum), add the Chicken Shack to your order, and apply the promo code CHICKENSUNDAY at checkout.
⚠️ The Fine Print: How to Make the Codes Work
- Order Channels Only: These coupons will NOT work if you order face-to-face with a cashier or use third-party delivery apps like DoorDash. You must place your order through an in-Shack digital kiosk, the official Shake Shack Mobile App, or online via shakeshack.com.
- Use All Caps: Shake Shack’s online checkout system can be finicky. Make sure you type both BONUSBURGER and CHICKENSUNDAY in solid capital letters, or the discount won’t apply.
- Exclusions: The freebies apply strictly to the base items. Any premium, paid add-ons like sliced avocado, extra bacon, or double/triple patties will be charged at normal menu pricing.
Offers are valid at participating nationwide locations only, so double-check your local Shack’s app dashboard before heading out. For more genuine ways to feed your family on a tight budget, head over to browse our full archive of active Free Food & Restaurant Savings Guides!
