Multi Item Shipping Discounts

This already exists. When you purchase multiple items at once, the shipping charges are less than the sum of the individual charges. For example, the shipping for a V2 by itself is $5.99. The shipping for a Pan Cam is $7.99. This adds up to $13.98. But if both item are purchased in one order, the shipping is $11.98.
