BROOKLYN PARK, Minn. (AP) - Gas prices have fallen another nickel over the past week to a national average of $3.61 per gallon.
That's according to Dustin Coupal (KOO'-pehl), a co-founder of GasBuddy.com. He says prices are down about 20 cents in the past month.
Coupal says the best place to buy gas is Greenville, South Carolina where it's $3.10 per gallon. Washington state has the highest prices -- about $4.26 per gallon -- due to supply distribution problems.
