Not all CartManager merchants have this feature enabled. If they do, you will see a link near the top of the billing address page that will allow a shopper to login or create a user.
This login allows us to store the shoppers address information so you won't need to re-enter it every time you wish to purchase.
If you don't have a user name, enter the username/password you would like, and check the new user box. If that username is available, you will be prompted to confirm your password on the next screen.
The customer login will store your address information. For security reason we require that you enter in your credit card number manually for each purchase.
