Gas prices are finally decreasing.

On average, the cost of a gallon of unleaded gas has dropped one or two cents every few days, for about three weeks, and it looks like it’s finally making an impact.

According to AAA, gas prices are down about 6% since their all-time high back in June, and that is due to a dip in oil prices and lower demand at the pump.

Data showed fewer people fueling up in the final weeks of June. However, AAA says July is a busy month for Americans, as many hit the road in the summertime.

According to Patrick de Haan, head of petroleum analysis at Gas Buddy, as long as oil prices stay low, drivers could see 1- to 2-cent per gallon price decreases every few days, with a potential low of $4 to $4.25 in another month.
