Free Chicken Sandwich Sundays Are Back
Shake Shack is running one of the best fast food deals of the fall: every Sunday, you can get a free food Chicken Shack sandwich or Chicken Shack lettuce wrap with a qualifying purchase of $10 or more in food or beverages.
The chicken sandwich deal runs every Sunday through December 27, 2026, at participating U.S. Shake Shack locations. The Chicken Shack sandwich and the Chicken Shack lettuce wrap each regularly sell for $8.99, so this is a solid savings on your Sunday order.
