There are a number of possible reasons as to why you are be receiving membership renewal reminder e-mails. One of the most common reasons is that you created a new Membership Subscription ID and the old Membership Subscription ID is no longer valid. Another possible reason is that you have downgraded or upgraded your membership type, and the reminder e-mail is for the old membership.
If you would like additional clarification on this issue, please e-mail us at customer.support@aofoundation.org and a staff member will contact and you.
