We have supermarkets over here that have their own gas stations. They are always running "specials" for cheap fuel, like buy $150.00 worth of groceries and get 10 cents per litre off your fuel. Make you wonder how they can do that when everyone else is charging premium prices. Our fuel prices bounce round too - at the start of the week it will be more expensive than mid week and when there is a holiday weekend the price goes up 5 - 10 cents per litre. Our government agencies are toothless and reckon they can't do anything to stop the oil companies price gouging.......
