Waitrose and M&S are far too posh and expensive for the likes of us Jos. Also, we're right out in the sticks, and try not to use up too much petrol. Asda and Tesco are reasonably convenient for us (although even they are a fair trek away!)

Personally, I like farmers' markets, little stalls and local produce.
We go to Roys of Wroxham where most of their stuff is locally sourced.
And we grow quite a bit ourselves. You should see our rhubarb at the moment, after all that rain - it's gigantic, like a triffid!
