I caught the tail end of it - what I saw was really good!
We're trying to buy mostly local -- the butcher & green grocer at the weekend and/or farmers market/city market. We're not 100% because we do pick up bits & bobs through the week at Morrisons if we need to, for convenience.
I'm going to start having our milk delivered as well, because we saw a program recently about how all the small dairy farmers are going out of business due to supermarkets buying mass-produced dairy.
