Shake Shack is known for its crave-worthy burgers, spicy sauces, and elevated fast-casual experience—but that premium flavor often comes with a higher price tag. If you’re ordering from Shake Shack regularly, there’s an easy way to save: by using Fluz to earn cashback every time you order. Here’s how to unlock more value from your Shack cravings.

What Is Fluz and How Does It Work at Shake Shack?

Fluz is a cashback app that lets you earn instant rewards when you buy digital gift cards for your favorite brands—including Shake Shack. Instead of paying directly with your credit card at checkout, you purchase a Shake Shack gift card through Fluz for the exact total of your order. Then, you pay with that gift card and immediately receive cashback.

Step-by-Step: How to Use Fluz at Shake Shack

  1. Download the Fluz app and sign up (it’s free).

  2. Search for Shake Shack in the app’s gift card store.

  3. Enter the exact amount of your order.

  4. Purchase a digital gift card and apply it during checkout—online or in-store.

  5. Receive instant cashback in your Fluz wallet.

Can You Stack Fluz with Shake Shack Rewards?

Yes. While Shake Shack’s loyalty program is still limited, the Shack App offers occasional promo codes, first-order discounts, and exclusive items. You can pay with a Fluz gift card inside the Shack App to stack cashback with in-app perks.

Example: Real-World Order Breakdown

  • ShackBurger Combo: $13.75

  • Fluz Gift Card: $13.75

  • Cashback: Earned instantly (based on the current Fluz rate)

  • Bonus: You can still use a promo code or app-exclusive offer within the Shake Shack app

Why It’s Better Than Coupons or Points Alone

Fluz gives you cashback upfront—no need to wait for a free item after 10 orders. You can still earn loyalty perks through Shake Shack while enjoying immediate savings from Fluz.

Final Thoughts

If you’re a regular Shake Shack eater, there’s no reason to pay full price. By using Fluz to shop discounted Shake Shack gift cards, you can enjoy bold flavors and build rewards with every bite. It’s a win-win for burger fans who crave heat, quality, and smart spending.
