Free shipping to US include Hawaii?

It's a shame I have to ask but many folks forget that Hawaii is a state and they do not say anything other than free US shipping in their ads. More than once I've placed an order with the idea that I would get free shipping as stated only to have the a ridiculous shipping charge tacked on.

I need two (more), BTW. It's a great product and the MPG is pretty darn accurate. (The HP & TRQ is another thing, though... ) I cannot give an OEM versus SGII comparison as none of my 4 vehicles has a stock MPG gauge.
