Plymouth and South West Co operative Society

The Plymouth and South West Co-operative Society Limited, known locally as Plymco, was founded in 1859 by ten tradesmen. The society grew from 18 members, as recorded on 3 January 1860, to a membership of over 130,000.

Members approved a merger with the larger Co-operative Group (of which the society was a corporate member) at a series of members' meetings during 2009. The merger occurred on 6 September 2009.
