If you’re only using a single rewards app when ordering burgers, you’re missing out. From loyalty points to cashback bonuses and credit card perks, stacking your rewards can turn your next $10 burger into a money-saving win. Here’s how to do it right—whether you’re dining in, picking up, or ordering delivery.
- Start with the Burger Chain’s Loyalty App
Every major burger chain has a rewards system—use it as your foundation.
- McDonald’s: Earn points toward free fries, sandwiches, and more
- Wendy’s: Redeem points for food and unlock app-only deals
- Burger King: Earn “Crowns” and get free upsize perks
- Pay with a Gift Card Bought Through Fluz
Before checking out, purchase a gift card from Fluz for the exact amount of your order.
- Why? You earn instant cashback—stacking savings on top of loyalty rewards
- Examples:
- Earn cashback with a Shake Shack gift card
- Save on Burger King orders
- Use a Cashback Credit Card for the Gift Card Purchase
When you buy a Fluz gift card using a credit card that offers cashback or dining rewards, you add a third layer of benefits.
- Best cards: Look for ones offering 2–4% back on restaurants or digital wallets
- Stack with a Cashback Browser Extension or App
If ordering online or through a third-party app like Uber Eats or DoorDash:
- Look for Bonus Challenges and Point Multipliers
Some apps run limited-time offers where you can:
- Earn double points for specific items
- Get bonus credit for ordering multiple times in a week
- Redeem small purchases for big redemptions (e.g., free sandwich after 3 visits)
- Don’t Forget Birthday and Referral Bonuses
Most burger apps offer free food or bonus points for birthdays and referrals. Combine those with your stacked strategy for a full-value meal with zero spend.
Example Stack (Shake Shack Order):
- Order total: $12.50
- Buy a $12.50 gift card on Fluz → Earn cashback
- Pay with that card in the Shack App → Earn any in-app promos
- Credit card rewards from Fluz gift card purchase → Additional cashback
- Use Rakuten if ordering for delivery → Final stack layer
Stacking rewards is one of the smartest ways to upgrade your burger budget. With just a few extra taps, you can save money, earn freebies, and make your favorite fast-casual meal work harder for your wallet.
