Andy Kev,
Yup, there's a British Shop in Basel, only about 20 mins drive for us. We do go there sometimes, but the prices are absolutely HORRENDOUS (actually, in common with the price of most other things here - I really do believe that our Govt is actually proud of the fact that we're the "hochsten kost inseln ins Europ)!!!!
Nevertheless, we have recently stocked up on Mincemeat from there (for the coming mince pies season of course).
And at present we're OK for PG Tips and Branston Pickle (regular visitors from UK now know better than to arrive without, otherwise they get turned away on the doorstep)! Pity we can't get decent fish n chips here - but to be fair, the above list is just about all I miss from UK, and I think it would be pretty hard to import fish n chips anyway, so I make do with "Felchen im Bierteig". It's "kinda OK" with "Dampfkartoffeln".
Edit for P.S. to Droogs: Just seen your post. Yup, Bider & Tanner in Basel, an excellent bookshop for English (and many other) books, also have an "English Corner" with all sorts of tempting goodies. We do partake from time to time, but again, the prices would blow yer socks off!
But all in all, "we get by" and frankly, for me anyway, I feel far more "at home" here than I do on my now infrequent visits to UK - and that's even without considering the current UK "political situation"
