The price of gasoline today is 147% higher than it was eleven years ago, but the CPI is up just 29.15%, May on May, 2002 to 2013 (latest available figures). So gasoline in Grand Rapids in July 2002 at $1.51 per gallon adjusted for inflation measured on "all items" arguably should be just $2.13/gallon today.
Instead gasoline's cheapest price today in GR is $3.73/gallon, 147% higher than in 2002.
What, oil companies weren't making a profit eleven years ago?
