In the century that followed, the society's activities expanded from food retail into a huge range of commercial, social and political activities. In 1902 it had over 20,000 members. Shops opened up in areas beyond Woolwich and house-building took place beyond the parish boundaries in Abbey Wood and Eltham. In 1924 membership had surpassed 100,000 and in 1938 this number had quadrupled. At its height (circa 1975), membership had reached 500,000 and sales exceeded £60 million. The society had outlets across most of South London and parts of Hampshire, Berkshire, Kent, Surrey and Sussex.
