Weavers Way is a cooperatively owned food market open to the public. Thanks to the dedication of their members throughout the years, a tiny buying club started by a few Mt. Airy neighbors in 1973 has evolved into a multi-store co-op serving more than 11,000 member households and their neighbors.
The Weavers Way Coop’s Mt Airy store has a property across the street called the Mercantile Building. It is home to The Mercantile which sells vintage collectables and the Nesting House which sells quality new and used items focused on young children and babies.
