It coordinates the organisation of regular sales of home-produced goods by individual producers.
All Country Markets are run co-operatively with no table dedicated to any individual.
The first Women's Institute Market took place in Lewes to sell surplus produce in 1919.
In 1932 the Markets were registered as co-operatives under the Industrial Provident and Friendly Societies Act 1893.
The Markets separated from The National Federation of Women's Institutes in 1995 and became self-financing.
