Shipping to a residential verses commercial address often costs more because of insuficent equipment to unload the parcel, and amount of time to do so. Zip into a commercial dock, fork truck runs in & out, and they're on their way. If the trucker has to wait for you to find your forks, drag the item to the back of the truck with chains that were in the barn out back, and also have a risk of getting stuck or not being able to navigate the trail to your house, this is why costs are higher. When you can, if you have a friend at a commercial facility, have things shipped there, then pick them up with your equipment.
