How do I change my membership card details and access my membership receipts?

Go to My Account (top right corner) > Login & Membership > section 'Billing Information' > click the button 'Manage your credit cards and subscriptions'. This will take you to a page with a number of links. For updating your card details go to the link 'Update my billing information'. To see your invoicing history, use the link 'View my order history'.
