If you have moved or wish for another reason to have your shipping address changed, you can do this relatively easily from your Backoffice.
To start, login to your Backoffice.
1. Click on your name in the upper right hand corner of the page, and click "Change Settings" in the resultant dropdown menu.
2. On the next page, the "Account Settings" page, click on "Addresses" in the menu on the left hand side of the page.
3. Now, click the "pencil" icon underneath your current address to edit that address.
4. Make all necessary changes to your address.
5. Make sure to set the correct address as your Primary.
If you will no longer be receiving packages at the old address, be sure to delete it entirely to prevent shipments from going there.
