The List feature allows you to create your own list (My Wish List) of items in your account. My Wish List is your own personal list that you can add items to for purchasing at a later date. It's not a public list and can only be viewed once you are logged into the store. You can move items between lists, move them to cart or delete them.
The List feature also allows you to create other lists (e.g. Gift Registry). The link for these lists can be emailed to friends and family for occasions such as birthdays, weddings etc., so they can purchase the items you have listed. You can create as many lists as you need and name them whatever you like such as Birthday List, Christmas List, etc.
After creating a new login account, you will see a screen asking you "What you want to do today?" To create your Wish Lists, click the link Create my wish lists. On the next screen, you will see a heading called "My Wish Lists and Gift Registry Management". Below that is a field to enter the name of your list. Click the Create New List button for your list. You can create as many lists as you need. Once the lists are created, you will have the option to add items to one of your lists instead of the shopping cart.
If you already have an account, click the "My Account" link below and login. You will come to the Account Details screen and you will see the Wish Lists and Gift Registries section where you can create your lists.
