Sometimes, an item does not have a 'buy it now' button and can only be purchased through 'Checkout' from shopping cart. To clear my Cart I want to delete it from my Shopping Cart and add it to a Shopping List.
1. Display my Shopping lists in a Split Screen on the right of my screen and allow me to 'drag' an item to a List.
2. Indicate if an Item I am viewing in my Shopping Cart is already in a specific Shopping List and indicate which one. Possibly allow me to delete it from a Shopping List if I plan to purchase it from my Shopping Cart.
3. Provide the ability to delete items from the Shopping Cart or Shopping List if the item is unavailable.
