Can I add multiple gift certificates to my Innergy account?
Only one Innergy gift card may be added to your account at a time. Once you have redeemed an Innergy gift card, you must wait until your subscription has ended to redeem and apply another Innergy gift subscription code to your account.
An annual Innergy gift card cannot be added to an Innergy account which is active with an existing subscription plan. Please wait for the subscription to expire before redeeming the gift card.
