Rupert, if you are looking for imported Cadbury items in your area, the rule of thumb I have always used is to look along the bottom of the wrapper and it will tell you where it is made. If it's Bournville, England...then you know you are getting the real thing. If it says Toronto then, of course, it is made there. I think the same goes for Mars Bars although I haven't found that much difference in taste between the the ones made here and the ones made in England.
