It's not sold in the states at least that I'm aware of.
Had to google it because I hadn't heard of it before reading your post.
Best bet might be a UK web site that will do international shipping.
Amazon has a some accessories too.
Thanks, it was skins I wanted, I'm buying it for my daughter but it looks a bit macho, wanted to soften it a bit, of course she wants an iPhone or a note2 but I won't get her anything that isn't almost indestructible. I know my daughter!!
