I wish it worked that way. The law is that you have to pay the tax rate of the city in which you take possesion. Since I had it delivered outside the city limits I saved 2.4% on the taxes.
Basically it goes like this:
2.4% of 7700= $184 (savings)
$184 - $50 (cost of delivery is nontaxable) = $134
extra 2 days wait = Torture
