Can you order it over the internet?
I'd love to say you can paypal me for shipping and I'll send a few to you. Sadly, with the archaic US alcohol shipping laws I cannot send even a single bottle to you.
That's too bad I'm a collector of Duff memorabilia when I can find it, I even almost got my hands on a Duff tap handle one time. I might try conacting the American distributor and see what happens.
