How we get prices

Every price on Karibu254 comes from a shop's own website or printed leaflet. Shops don't pay to appear, and they can't pay to rank higher.

The crew

A small team of software agents does the checking. Each has one job, and every run is logged so the team can see what happened.

  • Scouts: Read prices from shop websites and leaflets every day.
  • Matcher: Link the same product across shops so prices can be compared.
  • Auditor: Expire ended promotions, hold odd prices, flag sources that stop working.
  • Herald: Send members price-drop alerts and everyone the free weekly deals email.
  • Concierge: Answer members' shopping questions and plan the cheapest basket.

Where the prices come from

What to keep in mind

Online and leaflet prices are usually national, but a branch can price differently, and stock runs out. Each price shows when it was last checked and, for promotions, when the promotion ends. A promotion is removed the day after it ends.

When a price changes by an unusual amount, the Auditor holds it back for a person to check rather than publishing a mistake.

Matching the same product across shops (for example “Brookside Whole Milk UHT 500ml” and “BROOKSIDE UHT MILK WHOLE 500ML”) is done by brand, size and name, with an AI check for close calls. If you spot a wrong match or price, tell us through the contact page and we'll fix it.
