Can't get the free sample

The fine print on the bottom of the page offering the free sample kit says the offer is valid for Americans and Canadians.

However, I'm unable to select a Canadian province, but only an American state.

And when I filled in my Canadian postal code and then selected an American state just to satisfy the computer, it said "OFFER AVAILABLE IN U.S. ONLY"

So which is it?

btw, I cannot believe I had to go through more than 10 mins of work (between poise.com registration, uploading my printscreen into photobucket, and posting the link) just to ask you this d*** question
