When the coop merged with Somerfield they were forced to get rid of a certain amount of stores, I suspect that the Hazel Grove one was one of them. I cannot claim to be completely disinterested, but if you look at the breadth of stuff the Cooperative group does, over and above 'selling fair trade', and has been doing for years, I think that scores them a good few points over your Wallmarts and Tescos.
Oh and they have blummin nice wine
