So today I got gas at the bargain basement price of $136.4 a litre. Twenty days ago when the carbon tax came in British Columbians were paying about $1.54 a litre. How is it possible that gas has gone down by over 18 cents a litre in that time? There does not seem to be any rhyme nor reason for the prices we pay at the pumps. The only thing I can think of was that retailers were trying to profit over the long Canada Day weekend. I wonder what the price will be on the next long weekend??
