So we currently sell items by weight, however, very soon, we will be adding items with unusual dimensions (approx. 3.6 ft. x 4 in. x 12 in.). If a customer orders one item (whose shipping is calculated by weight) and another item (whose shipping is calculated by dimension), how is the shipping calculated for the entire order? Or more to the point, how should we set up the shipping with so many different item sizes?
Thanks for any help you can offer!
