At this time the app doesn’t update the balance on your gift
cards as they are being used. But you can keep track of your balances in the app. Go to your Wallet
and select the Gift Card, then tap the edit icon next to the balance. As you're shopping just update the balance as each card is used.
You can check the balance by using each merchants site. Look for the ‘check your balance here’ link in the Redemption Instructions.
