Gas Prices In Tennessee Fell Seven Cents Last Week, With The State Average Now At Two Dollars And Sixty-Eight Cents Per Gallon. That’s Eight Cents Lower Than A Month Ago And Forty Cents Lower Than This Time Last Year. AAA Says Lower Crude Oil Prices Contributed To The Drop, But Increased Gasoline Demand During Spring Break Travel Could Push Prices Higher In The Coming Weeks. Tennessee Is Now The Third Least Expensive Market For Gas In The Nation.
