Method and apparatus for optimizing orders for goods or services to increase a discount

A method and apparatus accepts a proposed order for products and/or services directed toward a vendor and identifies one or more additional orders that can be combined with the proposed order to obtain a higher volume discount than would be obtained submitting the proposed order by itself. One or more additional orders may contain a quantity of one product available from the vendor that, when combined with the proposed order, will qualify for the next discount higher than would be obtained by the proposed order alone and costs lower than cost of achieving the same discount using another product available from the vendor. One or more additional order may contain a quantity of one product in the proposed order that, when combined with the proposed order, will qualify for the next discount higher than would be obtained by the proposed order alone and costs lower than the cost of achieving the same discount using another product in the proposed order. One or more additional orders may contain all of the products in the proposed order that, when combined with the proposed order, will qualify for the next discount higher than would be obtained by the proposed order alone and is scaled so that the quantities of the products in the additional order are approximately the same as the quantity of products in the proposed order. The user can add one or more additional orders to the proposed order, and then submit the new proposed order.
