Cart.SubTotal is the total for the cart, after discounts are applied.
LineItem.ListPrice is the price before discount
LineItem.ExtendedPrice is the price for a lineitem, given the quantity of the item and applicable discounts.
LineItem.LineItemDiscountAmount is the total amount of discount for a LineItem.
