A 37-cent solution in July, 2003 (the date of creation of this nodeshell), would, as of August, 2024 (the date of the most recent data available at the time of this writeup), now be an estimated 63-cent solution according to the U.S. Bureau of Labor Statistics' CPI Inflation Calculator. That is just eleven cents shy of double.
The CPI inflation calculator uses the Consumer Price Index for All Urban Consumers (CPI-U) U.S. city average series for all items, not seasonally adjusted. This data represents changes in the prices of all goods and services purchased for consumption by urban households.
