After you have logged in to the Sanctuary, please go to the pull down menu by your name at the top of the website, and you will see a section called MEMBER OPTIONS. Please click on Member Options and you will find a link to change or update your payment.   Once you click on that link, you will be getting an email either from SPIFFY (they are the company that run and update the order form) or from STRIPE (they are our credit card processing company who are in charge of keeping your credit card data safe and for processing your monthly subscription fee).   The email you receive will have a secure link for you to click so you can change your credit card details.
