I've already seen hipsters building a coop supermarket. The idea that supermarkets jack up the prices, mistreat employees and blackmail providers is widespread (whether true or not). Those friends want to do good to producers and consumers alike and sidestep the "big evil companies". So some attempts exist and it's a good idea if poor-neighborhood coops invent better solutions than supermarkets concerning robbery and crime (only registered customers? know-your-customer schemes? the-boss-is-my-uncle effect?). However, I doubt they can have lower prices than supermarkets. Being a coop doesn't absolve you from margins and risk management.
