Not sure how many tins of beans a large artic carries but say 50000 tins of beans between the Heinz factory and Asda at 3p every couple of miles aint going to make much difference to the price of a tin of beans. Besides that, the fuel price was recently far higher than 3p litre more than it is now. Did the fuel price reduction make any difference to a tin of beans then......Nah.So you think its just 3p per litre what about everything you buy that gets the increase passed on???
