If you drive a car or truck, you will receive a nice surprise when you pull into a South Shore gas station today. After soaring to more than $1.43 two weeks ago, the price of gasoline has dropped by more than 6 cents a litre, literally overnight. A litre of regular self serve is selling at South Shore pumps now for $1.34.8. Thats the lowest price for gas around here in close to a month. The latest fall in prices reflects the lower world price of crude oil.
