I don't know the details of how much savings, but, it is cheaper to ship to a business address over a residence. When I bought wheels and tires from steeda, it would have cost me $250 shipping to NY, but because I had them shipped to work, it was only $125. That wasn't UPS, it was some freight company.
You should be able to go out to UPS.com and check the difference in pricing when you get a shipping quote.
