The national gas price average went up 1 cent on the week to $2.12, as motorists are now paying slightly more to fill up in nearly 30 states, with the vast majority paying just a few pennies more, according to AAA.

“Following a jump in demand, we’ve seen a number of state gas price averages increase on the week. However, the majority of these increases were just a few pennies,” said Jeanette Casselano McGee, AAA spokesperson. “With many states seeing rising COVID-19 case numbers and a number of officials warning against holiday travel, demand is likely to see a dip in coming weeks.”

On the week, South Carolina saw the largest increase, up 8 cents, followed by five other states who each had a 6 cent increase: Michigan, New Mexico, Indiana, Delaware, and Minnesota.

Despite the weekly increase, gas prices remain cheap both compared to last month (down 5 cents) and last year (down 48 cents).

The nation’s top 10 largest weekly changes were Ohio (down 9 cents), South Carolina (up 8 cents), Michigan (up 6 cents), New Mexico (up 6 cents), Delaware (up 6 cents), Minnesota (up 6 cents), Indiana (down 6 cents), Kentucky (up 5 cents), Georgia (up 5 cents) and Washington, D.C. (up 4 cents).

Meanwhile, the nation’s least expensive markets are Missouri ($1.76), Mississippi ($1.80), Oklahoma ($1.80), Texas ($1.80), Arkansas ($1.82), Louisiana ($1.84), Alabama ($1.86), Tennessee ($1.86), Kansas ($1.87) and South Carolina ($1.89).
