Don't be surprised if gasoline and heating oil prices increase overnight on the South Shore. Prices are up again in New Brunswick today for the third week in a row. The new maximum price there for regular self-serve is $1.27 per litre, an increase of 2.1 cents over last week's setting. Diesel is up nearly two cents a litre this week. Furnace oil has also climbed just over a penny a litre.
