We have a local one which we use occasionally, but we use it a lot less since it took out its organic fridge (fruit juice, ham, butter, milk, cheese etc) because there was apparently no demand .
It doesn't stock pull-ups for children aged over two, any organic fruit and veg at all, any fresh herbs or any non-dubious-looking meat. As other say, fine if you need some fairtrade coffee, tea or chocolate. But I think they are missing a trick tbh.
And the Co-Op generally is off my list after closing its excellent department store in our suburban high street. It's torn the heart out of what remained of a once-OK shopping centre
