Yes Hannah you are right.

But I am sure you would be able to get German sausages and bread there I know this as I have got my family hooked on them. The supermarkets stock Fleischwurst and German beers and so on so I am confident you can get plenty of German products in Wales.
I went to see a friend in Portsmouth a few months back and they served Hefe with the proper glasses and everything but they were impressed when I showed them how to pour it out of the bottle!
But I would like to add that I don't think diet drinks are necessarily British (or Welsh) products. I say the same for skimmed milk why can I only buy the long life stuff in Germany???
