What is the collective noun for Fairtrade coffee shops? Please send us your ideas… Our first one has been a “grind of Fairtrade Coffee shops”.

Wednesday 4th May sees the opening of M &S Food in Matlock and adds to the growing number of Fairtrade outlets in our Fairtrade town.

The new store will include a 25-seater M&S Coffee to Go cafe which will sell a range of Fairtrade refreshments.
