USPS offers bother weight based pricing and cubic based pricing. Cubic pricing works by multiplying the length, width, and height then dividing that number by 1728 which is 1 cubic feet. Weight and cubic have 2 separate pricing grids. When an order comes through, if cubic pricing wins, we want to make sure a cubic label is printed for the shipment to ensure we are billed correctly by USPS for the package, but we want the weight based pricing returned and marked up, then returned to our WMS. Weight based pricing should always be returned to the customer, whether or not cubic pricing would win or not. This is what we need to be able to do.
