Note: In Magento, quotes and shopping carts are logically related, but technically different. The shopping cart is a wrapper for a quote, and it is used primarily by the frontend logic. The cart is represented by the Mage_Checkout_Model_Cart class and the quote is represented by the Mage_Sales_Model_Quote class.
