Right now, they are running a truly epic promotion where you can buy any K-Shack item and grab a second one for absolutely free.
Whether you are craving the K-Shack Fried Chicken Sandwich, K-Shack Spicy BBQ Cheese Fries, or a sweet K-Shack Spicy Caramel Shake, you can mix and match to your heart's content. Just toss two qualifying items into your digital cart and drop the promo code SPICYSWEET at checkout! It is the ultimate budget-friendly date night or the perfect excuse to treat your work bestie. Plus, if you are looking to save even more cash this month, you can easily pair this adventure with other incredible March food deals or even Shake Shack's famous free Chicken Shack Sunday deal.
