shippers

A shipper is someone who arranges for things to be transported from one place to another. It could also be an object or a business that transports goods.

In common usage, a shipper can refer to either the person or the thing doing the transporting. For example, "My friend was the shipper who organized our move to the new house." In this case, the word refers to a specific person responsible for getting things from point A to point B. On the other hand, when you see an ad that says "Free shipping", it's usually referring to a business or company offering transportation services as part of their product package.
