Cheapest first means cheapest in this reading — the order of the prices as published, not what any of these forecourts is charging now. A forecourt that published no price for the selected fuel is listed with an em dash, left out of the ordering and out of the median rather than counted as zero. That is not evidence it does not sell it.
