To add a new address, click Add Address. Here you can add the details: name, phone number, zip code, and so on. Check Make this my default address if desired. Click Add preferences, notes, access codes and more if you wish to add delivery instructions, but this is optional. When done, click Add address.
To change details of an address, click Edit, make your adjustments, then click Save changes.
To delete an address, click Remove > Yes. Note that deleting an address doesn’t delete any pending orders going to that address; you should do that manually within Your Orders.
