Dropping oil prices are partly responsible for a drop of prices at the gas pump. Department of Agriculture fuels analyst, Harold Hommes (Home-us), says a lot of the state is seeing gas for under three bucks a gallon.

Hommes expects prices to continue to drop.

Crude oil prices dropped nearly six dollars or more this week — leading to the drop in gasoline prices. The Triple-A average price for regular unleaded gasoline in Iowa Tuesday was three-dollars, three cents. That is down nine cents from last week and down 25 cents from one year ago.
