How Supermarkets Work explains the history of supermarkets, how food arrives on store shelves, why stores are designed as they are, and what the future holds for grocery stores. Features include a glossary, websites, source notes, infographics, and an index. Aligned to Common Core Standards and correlated to state standards.
