We sell products from different departments - some departments want to set ship fees that vary based on # of items. Shipping cost increases as items increase (i.e. 1=$2.50 2=$4.00 etc). Other departments want to charge actual shipping costs on their orders. I tried to add a "shipping cost by item" option, but it shows up on every product along with the actual weight option. Is there a way to choose one shipping method for some products and other methods for others? - Barry
