I spent a month in the 'States and became addicted to this stuff...

It's called Snapple (you may have heard of it) and the flavour I'm addicted to is the original apple.
Now, I came across a few of the wrong flavour in an obscure newsagents the other day - giving me hope I might be able to track some down. So to this end, HAS ANYONE SPOTTED THIS OUT AND ABOUT? If so, WHERE?
