Yes, “time is money.” For e-commerce companies shipping packages to customers, weight is money as well. Generally, the heavier the carton, the more it costs to ship. Digging a bit deeper, this is commonly known in the transportation industry as Dimensional Weight or DIM weight.
DIM weight is a pricing technique used by shippers in which the SIZE of the box is correlated to its WEIGHT or conversely, the WEIGHT of the box is correlated to its SIZE. In either case, the carrier has pricing algorithms that allow for heavier boxes to be priced one way and bigger boxes to be priced another. To avoid higher shipping costs, you should strive to reduce your package’s weight and size as much as possible.
