@dvgmacdonald @bun pricestats, which is a commercialization of MIT's Billion Prices Project, is an independent collector of pricing data, which can serve as a check on government series. They too offer sectoral disaggregations, Apparel, Food & Beverages, Furnishing & Household Equipment, Health & Beauty, Energy & Transportation, and Recreation & Electronics. But I suspect access is expensive. pricestats.com/inflation-serie
