Teleportation is a made up technology so the rules around it are made up. But if we set some basic rules for it that are at least somewhat ground in science fiction.

You will probably need a receiving pad for the teleported items to arrive to as the earth is constantly moving through space so you need to anchor the teleporting location, that will probably be expensive

In order to follow the first law of thermodynamics where energy has to be conserved at the minimum the energy required for moving the goods will have to be used by the transporter and probably with some amount of inefficiency so if we say it takes the same amount of energy as it currently cost but with less labor and less warehouses it can easily cost several dollars and would scale based on distance

So you would probably be responsible for paying those energy costs and the teleporter pad costs
