There is an order online link just below the 'Find Store'. Check it out.
Did you check that? It's entirely possible that I miss some hidden 'enable international shipping' incantation here, but I doubt that at this point. The checkout form doesn't seem to include any of that and the very MS store front page lists the band as 'US only', just as I stated above.
Why? I .. fail to come up with an answer for that. I was prepared to hand over $200 right away, now I'm disgruntled and couldn't care less about another thing that might be available here in 3 month from now, maybe.
