Price history

The line shows the lowest observed price on each day prices were recorded. It breaks where there are no observations for more than a week.

How shop listings become one product

Shops name the same product in different ways. Hintapiste.fi joins their listings into one product with these rules, strongest first.

1. Barcode (GTIN)

   The shop’s listing carries the same barcode as the product. A barcode identifies the product and its version, so this is the strongest rule.

2. The shop’s own product id

   The shop’s own id has already been joined to this product once, so the same listing is recognised even if its name changes.

3. Brand, name and package size

   The brand, the normalised product name and the package size match. A similar name alone is not enough.

4. Stable address

   The shop’s product page keeps the same address, so the same listing is recognised by it.

5. Checked by hand

   A listing that no rule joins with certainty is checked by hand.

Why the cheapest comes first

• Order: offers with a price from cheapest to dearest, offers without a price last.
• Delivery cost does not affect the order when it is not known.
• In this snapshot the delivery cost is not known for any shop.
• The order does not depend on commercial agreements.
• Shop names are not links: the demo shows only prices and observation dates.
