When the CMA moves, this is what WEM can send the same day

What we can supply

• A 90-day price history for any product WEM already tracks — public page plus CSV, no signup. Example primitive: /history/….
• A same-day cut for a newly named retailer if that retailer is in the tracker. If it is not, we say so. We do not invent a chart from a homepage scrape on deadline.
• A verdict on an advertised “was” price only when the evidence bar below is met. Otherwise the verdict is insufficient_history — printable as “WEM could not judge”.

The evidence bar

Lifted from the scoring code in the published methodology, not rewritten for this page:

• 20 observations in the window (not the three the product page uses for a badge).
• Coverage on at least 50% of the window’s days — twenty samples in one week do not speak for the other eleven.
• We can prove a price was available (we recorded it). We cannot prove a price was never available (we sample; we do not watch). Missed dips stay unnamed.

Three example charts

Screenshot-ready. Each link is a live 90-day history. If a slug has fewer than three points, the page says tracking has started instead of drawing a line.

• Apple AirPods Pro 2

  A high-street “was/now” product journalists already screenshot.

  CSV

• Ninja Foodi MAX AF400UK

  The appliance category the CMA has already opened files in.

  CSV

• Dyson Airwrap Complete Long

  A named SKU with a long advertised “saving” — the chart is the test.

Founder quote — lift as-is

Tony Xhufi, Founder, WEM: “The Digital Markets, Competition and Consumers Act did not create a new kind of misleading price. It gave the UK a way to act on one that shoppers already knew. When a regulator names a retailer, the useful question is not whether the industry has opinions — it is whether that retailer’s advertised reference price ever showed up as the selling price. WEM samples displayed prices on a schedule and will only say a discount was not a real reduction when the observations clear a published bar. If they do not, we say we cannot judge. Silence is the honest product.”
