I might try it if I see one, although I've not been so keen on Cadbury's chocolate since Kraft got their mits on it.
I bought a Toffee Kit Kat when I went to the Post Office the other day, limited edition apparently. Very limited as far as I'm concerned, it was disgusting, really sickly. Instead of normal chocolate it has a pale toffee coloured covering that made me think of toffee flavoured white chocolate, yuk! - do Krafts make Kit Kat's now by any chance?
