Shake Shack isn’t known for being cheap—but that doesn’t mean you can’t save. With cashback tools like Fluz, burger lovers can cut costs without sacrificing quality. Whether you’re ordering a ShackBurger or a concrete shake, here’s how to earn cashback every time you check out.

How Fluz Works at Shake Shack

Fluz lets you earn instant cashback by purchasing digital gift cards right before paying. Instead of linking a bank account or preloading funds, Fluz allows you to:

• Buy a Shake Shack gift card for the exact amount of your order

• Use it immediately for in-store, kiosk, or online purchases

• Receive cashback instantly to your Fluz account

Where You Can Use Shake Shack Gift Cards

Fluz gift cards work seamlessly for:

• In-person orders at most Shake Shack locations

• Mobile orders placed through the Shake Shack app

• Online orders via shakeshack.com

You can enter the gift card number at checkout or scan the barcode from your phone in-store.

Stacking Rewards for Bigger Savings

• Use Fluz for cashback on the gift card purchase

• Earn Shack App Rewards (free fries, exclusive items) on mobile orders

• Pay with a rewards credit card to triple-stack the savings

Sample Savings Scenario

Let’s say you’re ordering a ShackBurger, crinkle-cut fries, and a drink for $14.32:

• Buy a $14.32 Shake Shack gift card on Fluz

• Get instant cashback (based on current rates)

• Earn Shack App points if ordered via mobile

• Pay with a cashback credit card for another layer of rewards

Bonus Tip: Don’t Preload—Pay When You Order

Unlike some apps, Fluz doesn’t require you to pre-buy and hold a gift card balance. You can purchase a card seconds before paying, making it ideal for spontaneous orders or last-minute cravings.

Final Thoughts

Shake Shack might not have a traditional value menu, but smart diners can still get value out of every order. With Fluz, you’ll earn cashback for food you were already planning to enjoy—and that’s a win worth stacking.
