After exhausting my Stateside options (Binny's did offer that they could obtain a bottle of the 3D2, FYI), I ended up ordering from:
http://www.scottishwhiskystore.com/shop ... -campbell/I was going to say that I had chosen this site over the one you posted, Ronnie, because it was much cheaper (46.03 pounds), but since my order, the price has risen drastically (I wonder if that's a result of my purchase?)
Even though he only got a picture of it for his actual birthday (today), he's very, very pleased and surprised by the prospect of its eventual arrival.
(note: I didn't deliberately wait until the last minute

-- it wasn't until he returned from Memorial Day weekend that he told the story about how this was his first favorite....)
Thanks, all!
