U.S. gas prices fall below $4 a gallon, AAA says

The national average for regular gasoline fell to $3.98 a gallon on Nov. 9, according to AAA data reported by Bloomberg, the first reading below $4 since mid-July. GasBuddy put the average at about $3.96, down nearly 16 cents in a week, MarketWatch reports. Despite the decline, MarketWatch says Thanksgiving travelers will likely face the highest gas prices since at least 2000.
