Log into your illumicrate.com account, and from there select the subscription option

From there, you need to select the 'shipping addresses' option on the menu bar. From there, you can either edit an existing address, or add a new one. 

If you add a new address, you will need to fill in all the required fields

Once that's done, you will need to press 'next' so you can select a payment method to add to your subscription

You will then need to ensure the new address is associated with your subscription. To do this, navigate to the 'subscriptions' section of your account and then select the relevant subscription

Scroll down to the 'shipping and billing' section and click it, to then select another address

Please note, you do need to update your address within the subscription section for it to apply to your subscription. Adding/updating your address within your general illumicrate.com account will not apply to your subscription/s.
