You can redeem any credits when you set up a bill payment in your account on Spritz. You'll have to apply the total amount of your credits to the bill payment you'd like to redeem them, but you can stack credits you've earned and apply them all toward one payment!
To redeem your credits, click on the button to apply your credit balance and then confirm the transaction once the credits have been applied. Credits can be used to pay bills, off-ramp, or they can be added to your Spritz Card.
