This could be a fore-runner of what may happen overnight tonight with South Shore gas prices. For a third straight week, the price of gas is down in New Brunswick. Regular self-serve fell an even two cents last night to a new top price of $1.23 a litre. Diesel has dropped three-tenths of a cent and furnace oil has fallen just over a penny to a new maximum price of $1.06 per litre. The prices are at their lowest level in New Brunswick since last Christmas.
