You can switch your subscription from Quarterly to Annual at any time. Once you have switched you will be charged the Annual rate when your Quarterly subscription normally comes up for renewal.
To switch your current subscription, please follow these steps:
Log in to your account using your credentials.
Visit the “My Account" page.
Under My Subscriptions, click the Change Subscription button next to your active subscription.
You will be taken to the Black Gold product page, and you can choose which billing cycle you prefer. Progress through this process to complete your payment and confirm the switch.
