group places importance on ethical and transparent trading and reporting, and democratic accountability and participation. Individual stores may have member forums. Unlike a pure consumer co-operative, voting rights are shared between the corporate members and the individual consumer members, as described in an annual report: Voting for corporate members is in proportion to trade with the society. Each individual member has one vote in the appropriate region of the society and each region has voting rights calculated on the same basis as a corporate member.
