New York (CNNMoney.com) -- Gasoline prices fell for the 52nd straight day, according a survey released Saturday by the motorist group AAA.

The average price of regular unleaded decreased to $2.282, a 3.2 cent drop from Friday, according to the national survey, which is based on credit card swipes at gas stations. Before this week, the last time prices were this low was on February 24, 2007, according to AAA.

Over the last 52 days, prices have sunk $1.57, a 41% decrease.

Demand for gasoline has continued to slip, despite the fall in gas prices. MasterCard's weekly survey of gas station credit card swipes showed demand down 3.9% last week, compared to the same period last year.

Prices have dropped 44.5%, or $1.83, from their record high of $4.114 a gallon set July 17. The average price per gallon dropped below $3 on Oct. 18, the first time in nearly nine months.

By state, Alaska reported the highest average gas prices, $3.36 per gallon, while Missouri boasted the cheapest, at $1.966 a gallon.

Gasoline prices have fallen while average crude prices have done the same in the past four months. U.S. crude for December delivery settled at $61.04 a barrel in New York trading on Friday, down from its high of $147.27 a barrel on July 11.

Only two states, Alaska and Hawaii, have average gas prices above $3 per gallon, while 43 states report prices below $2.50 per gallon.

The AAA figures are state-wide averages based on credit card swipes at up to 100,000 service stations across the nation. Many drivers have reported even lower prices across the country.
