Shake Shack gives away free chicken sandwiches every Sunday this July

In a bid to celebrate National Fried Chicken Day, Shake Shack, a popular fast-food chain based in the United States, is launching a promotional offer. This limited-time deal runs every Sunday from July 6 through July 27, 2025. Customers making a minimum purchase of $10 will be able to receive a complimentary Chicken Shack sandwich. This promotion is particularly significant as it combines a seasonal celebration with a customer incentive, aiming to boost sales during the summer months. The promotion is structured to only apply to qualifying orders placed at in-Shack kiosks, through the Shake Shack mobile app, or via the official website shakeshack.com. Importantly, the offer is restricted to participating U.S. locations, and customers must use the promo code 'CHICKENSUNDAY' at checkout to redeem the offer. The code is case-sensitive, indicating that customers must enter it in all capital letters to avoid any issues during redemption. Such attention to detail emphasizes Shake Shack's intention to smoothly facilitate customer engagement with the promotion. While the offer encourages customers to order more, it does have specific restrictions in place. Customers must meet the $10 minimum requirement through food or beverage purchases, which can include burgers, fries, hot dogs, shakes, or drinks—but does not apply to the free Chicken Shack sandwich, taxes, fees, or gift card purchases. Additionally, the promotion excludes certain items such as BBQ chicken sandwiches, chicken bites, and paid add-ons like avocado or bacon, to maintain clarity on what qualifies for the deal. Customers should also note that the offer is not valid for drive-thru orders or through third-party delivery apps, limiting the ways in which the promotion can be accessed. This strategy may be positioned to encourage in-person visits to their locations, which could potentially lead to increased overall sales. Moreover, the limitations on the number of free Chicken Shacks—only one per order, and the inability to combine the deal with other promotions—suggests a deliberate move to manage the offer's impact on the business’s bottom line. Overall, this promotion allows Shake Shack to foster customer loyalty while celebrating a national food holiday.
