Does ShipStation automatically select the cheapest shipping option?

At this time, ShipStation does not automatically select the service with the cheapest rate. To compare rates, use the Rate Calculator.

You must determine what shipping service your packages will use. You can automate this process using product defaults, service mapping, or automation rules.
