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.

DE1 is one of 8 postcode districts in Derby. Every forecourt in Derby is ranked against every other on one page, with the districts of the town set beside each other — which is the comparison this page cannot make, because it holds one row of it.

A postcode district is a sorting boundary, not a driving one. Both of these measure from the middle of the forecourts we hold in DE1 — a point we derived, not your address — and both cross into neighbouring districts wherever the forecourts are.
