I'm sure there has to be a law somewhere about selling something as a quantity with an ilegal price.
another example, so supermarkets sell mars bars at 55.25p each.
So you cant buy one you have to buy 4 or none.
People would soon switch to snickers, or maybe the sale of mars bars, would actually increase, who knows,
but with fuel they know they have you by the balls and pretty much do as they please.
Bring back the horse and cart and barter for "goods"
