Average retail gasoline prices in Missouri have fallen 4.1 cents per gallon in the past week, averaging $3.45 per gallon yesterday.
This compares with the national average that has fallen 0.1 cents per gallon in the last week to $3.66 per gallon, according to gasoline price website MissouriGasPrices.com.
Including the change in gas prices in Missouri during the past week, prices yesterday were 84.7 cents per gallon higher than the same day one year ago and are 7.2 cents per gallon higher than a month ago.
The national average has increased 5.1 cents per gallon during the last month and stands 93.3 cents per gallon higher than this day one year ago.
"Late last week we started to see a drop in wholesale gasoline prices, which is the price stations pay. Such news means the national average may begin moving lower," said Patrick DeHaan, GasBuddy.com Senior Petroleum Analyst.
"While I'm hopeful we'll start to see lower retail gasoline prices in the days ahead, we have seen considerable volatility and I'd hate to see the market move higher in the days ahead, negating any expected drop in retail prices," DeHaan adds.
