If you'd like to change the shipping address associated with your Stix subscription, you must have created to a Stix Account. That's where your subscription is managed. Here is an article on creating and activating a Stix account.
Once you have an active account, here are the next steps:

From there, you can add a new address or select a previous address. Note: Please be be sure you select 'Set As Default' after making your new selection.
