- Replies 0
Summer may be winding down, but Shake Shack isn’t letting the season slip away quietly.
To mark the end of summer, the popular chain is rolling out a special promotion that lets customers enjoy one of its barbecue sandwiches for free.
Fans of smoky, tangy comfort food will see this as a perfect chance to indulge without stretching their budget.
The deal is only available for a limited time, making it all the more tempting to act fast.
Whether you’re a longtime Shack regular or new to the menu, this giveaway is worth checking out before September officially arrives.
From August 21 through September 1, 2025, Shake Shack customers who place a digital or kiosk order of $10 or more can add a free Summer BBQ sandwich to their meal.
To redeem, just enter the promo code SUMMER at checkout.
The offer is available at participating locations, but keep in mind it excludes certain outlets such as San Diego, Detroit, airports, stadiums, travel plazas, and museums.
The discount is capped at $13.49, and only one free sandwich may be claimed per order.
Shake Shack’s summer barbecue lineup has been a limited-time highlight since April, and this promotion gives customers one last chance to enjoy it.
Choices include four different sandwiches, available as either burgers or chicken:
Each sandwich typically costs around $10.49, but this deal makes it free when paired with another $10 purchase.
Redeeming the promotion is simple:

End-of-summer promotions are a restaurant tradition, but for Shake Shack, there’s a strategic angle, too.
Digital orders—through the app, website, or kiosks—now account for about 38% of total sales, and promotions like this encourage customers to stick with those channels.
It’s also a way for the brand to keep momentum going with a limited-time menu that’s proven popular since spring.
Want to stretch the promotion into a full Shack experience? Here are a few ideas:
Shake Shack began as a single hot dog cart in New York City’s Madison Square Park before evolving into an internationally recognized chain.
Known for fresh ingredients and inventive spins on American comfort food, the company continues to experiment with seasonal menus like this barbecue collection—keeping things fresh while staying true to its roots.
