How KDCompare works

Where prices come from

Prices come only from sources that permit their use: official retailer APIs, authorised affiliate product feeds and merchant catalogues. We do not bypass access restrictions or read websites without permission.

How merchants are included

A merchant appears when a legitimate data source exists for its offers and it delivers to the market in question. An offer is only shown in the countries it applies to.

How offers are matched

Offers are matched to a product by GTIN/EAN or by brand and manufacturer part number – never by a similar name alone. New, used and refurbished items and different variants (e.g. storage size) are kept separate.

How offers are ranked

The default is lowest total price: product price + shipping + known mandatory charges. Where shipping is unknown we show “Shipping cost unavailable” and list the offer after those with a calculable total. Commissions and sponsorship do not affect this order.

Freshness

Every offer shows when it was last checked: “Fresh” (up to 24 h), “Recently updated” (up to 72 h), “Stale” (older). Offers not confirmed for more than 14 days are no longer shown. Unusual price jumps are reviewed before they are displayed.

Limits of our data

Prices and availability can change at any time. The price on the retailer's website at the time of purchase always applies. Please report errors via the contact page.
