Barclays Bank Chelmsford had a pop-up business section running in December this year. I stopped to chat to the people from Wakelin's Premium Coffee who were there. Apparently they are local, but do not trade here or have a web site at all. They sold beans or ground beans at £2.50 for a 250g bag. Two bags were purchased (blends, which are not my normal thing): House Blend and Italian Passion.
