SC gas prices increase by about 10 cents this week

CHARLESTON, S.C. (WCIV) -- The average price for a gallon of gas in South Carolina has increased by 9.8 cents in the last week, according to Gas Buddy, a website that tracks prices at gas stations across the country.

The current average price for a gallon of gas is $3.13.

The national average has increased 5.1 cents per gallon in the last week, making it about $3.26 per gallon.

Gas Buddy analysts note the next week will prove interesting for gas prices as developed countries made progress with Iran's nuclear ambitions this weekend.

"Just that action alone may result in significant downward pressure on oil prices as tough sanctions may soon be eased, allowing Iran's oil to flood an already well-supplied marketplace," said Senior Petroleum Analyst Patrick DeHaan.
