When you receive an invoice from our payment service to remind you that your subscription will renew, it will include the base price of your subscription. However, this does not include any Gold credits that you may have. For instance, if you have 6 unused Gold credits, and your subscription is $84 a year, your invoice will show that you'll pay $84, however you will actually be charged $42.

You can check to see how many unused credits you have by going to your profile, tapping on "Your Subscription" and tapping into "Credits".

Anything under the "Unused" section will be applied to your next renewal.
