Lundberg said the price has dropped 65 cents since its peak in May and is 29 cents below what it was last year.
She said the drop has been driven by a decrease in the price of crude oil. She forecasts minimal further cuts if prices remain stable.
In the Lower 48 states, San Francisco had the highest average price at $3.45 per gallon, while Memphis, Tennessee, had the lowest average at $2.73.
