COLUMBIA, S.C. (WCIV) -- Average retail gas prices rose across the state by nearly 2.5 cents last week, while national prices fell by almost the same rate.
"The national average has continued its downward decline in the last week, likely being helped by relief in the Great Lakes, a region that had been plagued with refining issues that have seemingly been resolved," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan.
The average price across the state was $3.23 per gallon, according to GasBuddy.com. That's 17.5 cents higher than one year ago and 0.9 cents higher than the average prices one month ago.
Nationally, prices dropped by 2.1 cents to $3.61 per gallon, the website reports. The national average has decreased 5.0 cents per gallon during the last month and stands 8.0 cents per gallon higher than this day one year ago.
"While the national average stands higher than it did a year ago, we likely will see the average decline, and for motorists in the Great Lakes, the downward trend should mean well needed relief at the pump. Areas of California may see prices rising slightly in the days ahead, but at this time we aren't seeing any short term price spikes across the United States," DeHaan said.
