Ordering from J-List requires both a billing address and shipping address.
Registered users can manage their address by logging in to their J-List/JBOX account and going to "Address Book" at the account dashboard. From there, you can add, delete, or edit addresses plus set your default billing and shipping address.
Changes made to your address book will not reflect on orders you have already placed.
To change the address of an unshipped order, please submit a ticket.
