Farm-to-retail price spreads are reported for a 3-pound grocery pack of shortening during 1947-68 and for a 24-ounce pack of salad or cooking oil during 1964-68. Retail prices for major and minor brands are evaluated, as are types of retail outlet in six U.S. areas. Farm-retail spreads have widened in the last 20 years; most of the increase has been for costs of services, since the farm value of the oils does not reflect strong change. Striking price differences appear between advertised and unadvertised brands and among the different types of retail outlets.
