A fan-favorite is offering free sandwiches this July—don’t miss the details

It’s officially the heart of summer, and for some, that means heatwaves and weekend plans.

But a well-loved name in fast food is giving folks across the country something extra to look forward to each Sunday.

Without much fanfare, they’ve launched a deal that could have your next lunch covered—for free.

If you enjoy crispy chicken and a little savings, you’ll want to take note of how to claim yours this month.



Throughout every Sunday in July, a free Chicken Shack sandwich is up for grabs, thanks to a limited-time offer from Shake Shack.

The deal is part of the brand’s celebration of National Fried Chicken Day, and it runs through July 27.

To qualify, customers must place a minimum $10 order on Sundays and apply the promo code CHICKENSUNDAY.

Eligible orders must be made through the Shack App, the official Shake Shack website, shakeshack.com, or in-store at the kiosk.

Orders placed through third-party delivery services or drive-thru lanes will not qualify for the promotion. Each free Chicken Shack sandwich must be redeemed per qualifying order—no stacking or multiple redemptions per transaction.

The promo excludes several other chicken options such as the Smoky Classic BBQ Chicken, Carolina BBQ Chicken with Fried Pickles, Avocado Bacon Chicken, and Chicken Bites.

Additionally, add-ons like avocado or bacon won’t be included and must be purchased separately.



The featured sandwich itself is made with a fresh, antibiotic-free chicken breast, seasoned and cooked daily to maintain quality and flavor.

Customers often praise the sandwich for its juicy texture and thick cut, making it a popular pick from the restaurant’s menu.

Whether you’re a longtime fan of the chain or just curious to try something new, this promotion offers a great way to enjoy a well-loved menu item without stretching your budget.

As always, double-check your order and promo code entry before checkout to make sure your deal qualifies.

This summer, a free sandwich might be just the right reason to treat yourself—or someone else.
