The national gas price average pushed a penny cheaper on the week to $2.11 following an increase in gasoline stocks and a dip in demand, according to AAA.

“As some states increase travel restrictions and others roll back reopening processes, demand is positioned to weaken, though not likely drop as low as we saw in March and April,” said Jeanette Casselano McGee, AAA spokesperson. “That translates to a continuation of cheaper gas prices at the pump.”

On the week, only four states saw gas prices increase: Indiana (up 6 cents), Ohio (up 6 cents) and Illinois (up 2 cent) and Washington, D.C. (up 1 cent). As has been the trend for weeks now, the majority of states gas price averages continue to push cheaper. Nearly 20 states start the week with an average at least three cents cheaper than last Monday.

Today’s national average is seven cents cheaper than last month and 51 cents less expensive than last year.

The nation’s top 10 largest weekly changes were Delaware (down 7 cents), Indiana (up 6 cents), Ohio (up 6 cents), Michigan (down 4 cents), Florida (down 4 cents), Texas (down 4 cents), Maryland (down 4 cents), Kentucky (down 4 cents), Georgia (down 4 cents) and Missouri (down 3 cents).

Meanwhile, the nation’s least expensive markets are Missouri ($1.76), Texas ($1.77), Mississippi ($1.78), Oklahoma ($1.78), South Carolina ($1.81), Arkansas ($1.81), Louisiana ($1.83), Alabama ($1.84), Tennessee ($1.85) and Kansas ($1.88).
