Questions we can answer that a shop cannot

• How much does an electric skateboard cost?
  The full distribution — not a single number — for boards, scooters, bikes and unicycles.
• What electric skateboard parts cost
  Median prices by category, for everything that wears out or breaks.
• How many advertised discounts are real?
  Every crossed-out price, checked against what another shop charges the same day.
• Is Black Friday actually cheaper?
  Twelve months of dated captures, each compared against its own page.
• Do prices go up or down over time?
  What a decade of archived snapshots says a price actually does.
• What costs less today than it did years ago
  Products cheaper now than a dated capture of the same shop, with the capture.
• What a board costs, country by country
  Each market in its own currency — and why we never convert between them.
• Which brands can actually be price-compared?
  How few brands more than one independent shop carries.
• What sold out at every shop that had it
  The one stock measurement no single merchant can make about himself.

Every figure is read from the database as the page is built, and none is written by hand — so a study cannot go stale between visits, and there is nothing to update when the measurement changes. The wording of each question never changes: the URL is the question's identity, and a page cited last week has to still be answering the same thing this week.

Each page states what it refuses to conclude. That section is not modesty; it is the part a reader should check first. How this works →
