Inter Commercial shipments between 2 shops, with UPS accounts costs Less than a residential one , I suspect Largely because
Odds are Nobody will be Home, at residences, and they may have to call back More *than Once.

For a Business they drop ship to's: during the Business day , (our LBS gets Touring Cyclists Bikes during the summer ,
then they Skip the hauling the carton out of the airport and Onto the Bus to Get here)

& they ship them out when they Get here after a transcontinental Ride.
