In 1946 a federal court convicted the world's largest grocer of what was essentially selling food too cheaply. The episode follows A&P's roughly 15,700 cash-and-carry stores and house brands, Clarence Saunders's self-service patent, and the independent merchants' counterattack through chain-store taxes, a proposed federal death-sentence tax, and the Robinson-Patman Act of 1936, whose revival by the FTC in 2024 shows it is no museum piece.
Economists mostly read A&P's low prices as scale and efficiency, while the court's findings of discriminatory supplier preferences support a squeeze reading. Whether Robinson-Patman helped small merchants is also disputed, since it blocked independents' buying cooperatives.
