Does this data get sold to hedge funds or other groups? Companies that process large amounts of purchases must have some of the most accurate data sets on consumer spending that can exist, and should be able to get that data up to date for a time period much faster than any company or gov could compile a survey. Amazon, Shopify, Square, Visa, Mastercard, etc they could all easily calculate inflation easier and more accurately than the gov.
