You can get them in some other Countries, Australia (though they are only available at the Cadbury factory outlet in Hobart, Tasmania), Britain, Germany and South Korea.
Mr. Big Canada is chocolate bar crazy, we have quite a few others that are available in EVERY store in Canada but very rare outside the country. More and more they're starting to catch on.
Smarties, Crispy Crunch, Coffee Crisp....damn if it wasn't snowing like the world was ending I'd be going for chocolate right now.
