How we rank
This page explains what we sort by and how much each criterion weighs. If what you read here does not match what the site does, the mistake is ours: tell us.
The default order is the total price
On a product page, offers are sorted by total price, lowest first: the product plus shipping, tax included. We do not sort by the price without shipping, because that changes who comes first.
In category listings we sort by the lowest total price each product has at that moment, and you can switch to "biggest drop" or "newest" with the selector.
Pages we currently have no live price for appear at the end, in all three orders, and say so. They are there because they have a specification sheet with its source and a verdict written by a person, which can be read even if it cannot be bought today. What we do not do is show their last known price as if it still held.
Nobody pays to rank higher
We do not charge shops to be listed or to be listed higher. If we ever accept a paid placement, it will be labelled "sponsored" next to the shop name, and it will still sit where its price puts it.
We earn a commission from the shop when you buy through our links. That commission plays no part in the ranking.
Which offers are shown, and when they disappear
Every offer we receive has an expiry. Once it passes, the offer stops being shown: we do not display a price we can no longer stand behind, even if that leaves a product page with no offers at all.
We also drop offers that are out of stock. Next to every offer table we show the time of the last update.
How we know two offers are the same product
We match on the EAN barcode, or on the exact brand and model code with a price inside a sensible range. Anything unclear is not published: it waits as a proposal until a person reviews it. The methodology page has the full rules.
"Biggest drop" and the 30-day low
The drop shown on a card compares the current lowest total price against the highest price we ourselves recorded in the last seven days, in the same market.
When we announce a discount on a product page, we compare it against the lowest price of the previous thirty days, which is the reference the law requires. That figure is always written next to it, so you can check.
A price history of our own
We store every price change of every offer from the day we started tracking it. The chart on the product page comes from that, not from a figure handed to us by a shop.
