Bwiti, I do believe they have a way of telling instantly if you are in a bussiness zone or not. I once tried claiming I was at a bussiness location to get a reduction on the shipping costs, as it was more to ship to a residential location, and the rep knew somehow that it was a residence, triggering the blonde in me, "ohh, gee wiz, I thought I lived in a bussiness zone.. well, now I know!"
