"Chicken Sunday" Deal Back at Shake Shack Through End of 2025

Shake Shack has brought back its Chicken Sunday deal, where you can get a free Chicken Shack sandwich with an online purchase of $10 or more on Sundays, through the end of the year. It is also offering a buy-one-get-one deal on the Smoke Shack burger throughout November.

The Chicken Sundays deal can be redeemed when ordering through an in-restaurant kiosk, the Shake website, or the Shake Shack mobile app on a Sunday through December 28, 2025, using the code "CHICKENSUNDAY". The Smoke Shack November BOGO deal is also available using the same ordering options, only using the code "SMOKESHACK" instead.

Shake Shack's Chicken Shack is the chain's fried chicken sandwich. It features a crispy-fried chicken breast filet, lettuce, pickles, and buttermilk herb mayo on a toasted potato bun. Prices vary, but it normally costs $9.49 here in Los Angeles.

The Smoke Shack is a burger that features a quarter-pound Angus beef patty, American cheese, applewood-smoked bacon, chopped cherry peppers, and ShackSauce on a toasted potato bun. It normally costs $9.99 near me.
