I'm in the north east, and not even in a major city, so the selection is very limited. Like, I could drive 15 minutes to the nearest "local" bakery but then like I said, anything that isn't just your normal toast bread is stupid money per loaf because it's "artisinal".

>>The UK also has some very good mills and we're spoilt for flour

That's interesting, because I find the exact opposite - not in terms of quality of course, but in terms of variety. I find that usually you only have your normal plain, then self-raising, then maybe two types of wholemeal....and that's it. In Poland where I'm from you'd get at least 10 different types of normal white flour in every store, based on how finely they are ground and how pure they are(denoted as "type" from 450 to 2000), and then you have flour from Poznan, from Warsaw, from Wroclaw etc etc - all found in normal stores. In UK it's just "plain". Tesco's own brand or maybe one other "named" brand.
