By default, all new shopper sessions start as an anonymous shopper profile.
All of the items added while in anonymous mode can be saved to a newly created profile or existing shopper profile.
The shopper may checkout anonymously as a guest shopper or the associate may identify and login a shopper at any point during the session, including checkout.
Any carts that are created for an anonymous shopper are discarded at the end of a session if they are not saved by identifying the shopper or by creating a new user account.
