Use Fluz to maximize rewards on your Citibank payments. Instead of paying your credit card, loan, or mortgage bill directly, buy a Fluz gift card for the amount due and use it toward your payment, earning cashback on money you already owe. Fluz stacks with other rewards programs, so you can layer this cashback on top of your Citi ThankYou Points or cash back rewards. It's a simple way to turn a routine bank payment into extra savings, with cashback credited straight to your Fluz wallet.
