Use Fluz to maximize rewards on your Comerica (now Fifth Third) Bank payments. Instead of paying your loan, credit card, 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 any other perks you're using. It's a simple way to turn a routine bank payment into extra savings, with cashback credited straight to your Fluz wallet.
