our local asda is the cheapest station around.... just not normally passing it when I need to fill up
its only a couple of min a way, so I can always go buy that way, there 2p cheaper anyway... so with the extra 4p a liter on a £60 tank full adds up
specially when Im filling up like that 2 or 3 times a week
p.s. just waiting for them to send me the paperwork to sign and Ive got one
