Postage refers to the fee charged for the service of transporting letters, packages, and other mail items from one location to another. Typically, it is determined by the weight, size, and distance being sent. In the context of shipping or fulfillment, it usually includes the cost of packaging, labor, and delivery to the recipient's address.

What factors determine the cost of postage?

The cost of postage is determined by several factors. Firstly, the weight and size of the item being shipped play a major role. Heavier and larger items require more resources to transport and thus incur higher postage costs. Secondly, the distance between the origin and destination also affects the cost. Longer distances require more time and resources for the transportation process. Lastly, additional services like insurance, tracking, and expedited delivery can also increase the overall postage cost.
