Grab a free Shake Shack sandwich with any $10+ purchase through Dec. 31, 2025, using promo code SHACKCHEER — each week features a new freebie!
You know that sweet little thrill you get when you find a freebie that also happens to involve burgers? Same. And Shake Shack is basically handing out December happiness wrapped in a warm, toasty bun.
If you’ve got a Shack nearby, you might as well call this your “treat yourself” month — because free sandwiches are officially on the menu.
Why This Freebie Is So Dang Good
Shake Shack doesn’t run promos like this often, which makes this one feel like a mini-holiday miracle. Every week through Dec. 31st, you can score a different free sandwich when you make a $10+ purchase and use code SHACKCHEER.
They’re rotating through fan-favorite sandwiches, so you can basically make December your own little taste-testing tour. Also, no coupons to cut, no sweepstakes form to fill — just order, enter the code, and enjoy your freebie.
Weekly Free Sandwich Lineup
Just to keep things exciting, Shake Shack is switching up the freebie every few days:
- Dec 1–7: The Big Shack
- Dec 8–14: SmokeShack (single only — no doubles or triples)
- Dec 15–20: Chicken Shack (excluding Avocado Bacon Chicken & Chicken Bites)
- Dec 21–31: ShackBurger (single only — no doubles or triples)
How to Claim Your Free Sandwich
- Visit a participating Shake Shack in December. Any location that accepts app/online orders should work.
- Add at least $10 worth of food to your cart. (Easy — have you seen their fries?)
- Add the weekly eligible sandwich to your order.
- Use code:
SHACKCHEERat checkout. This applies the discount and makes your sandwich free. - Pick up your meal, snap a pic if you’re feeling cute, and enjoy your freebie.
Check dates carefully! Each sandwich is only free during its specific weekly window. Expires: December 31, 2025
No purchase necessary? Sort of — you do need the $10 purchase, but the sandwich is totally free.
About Shake Shack
Shake Shack started as a simple NYC hot dog cart and somehow turned into a full-blown global burger obsession. People love them for their juicy burgers, crinkle-cut fries, hand-spun shakes, and that signature Shack Sauce that basically has a cult following.
Fans rave about the quality, the consistency, and the fact that the brand keeps things fun with seasonal menu items and customer-friendly promos like this one. Whether you’re team burger or team chicken, their ingredients always feel a step up from your typical fast-food chain — which makes getting one for FREE feel extra satisfying.
More Freebies
If you love stacking small wins into a whole-day vibe, here are a couple more freebies you can grab while you’re at it:
- Free Good To Go Soft Baked Fibre Snacks — Perfect for tossing in your bag for later.
- Free Comvita Manuka Honey Drops — A cozy winter treat, especially if the cold weather is doing the most.
Don’t Miss Them
This is one of those rare “don’t wait” freebies — Shake Shack has a huge fan base, so expect lots of people grabbing these deals each week. If you’re planning a burger night anyway, you might as well pick up a free sandwich while you’re at it.
Tap over, place your order, and enjoy your tasty December freebie run.
