If the shipping address was entered manually, then we instantiate a ``ShippingAddress`` model with the appropriate form data (which is saved in the session). If the shipping address was selected from the user's address book, then we convert the ``UserAddress`` to a ``ShippingAddress``. The ``ShippingAddress`` instance is not saved as sometimes you need a shipping address instance before the order is placed. For example, if you are submitting fraud information as part of a payment request. The ``OrderPlacementMixin.create_shipping_address`` method is responsible for saving a shipping address when an order is placed.
