Affiliate disclosure

We may earn a commission when you buy through some links. This never changes how we rank products or prices.

How ranking works

Offers are ranked by the stated criterion only — lowest total price, best match, or best value. Commission is never an input. If the cheapest retailer pays us nothing, it is still shown first when it is the cheapest.

What we label

We never use the word "best" without saying what it is best at. Every offer links to the retailer's real product page, and we show when the price was last checked.

Why we do it this way

The service only works if you can trust it. A commission that changed the answer would destroy the product's only real asset.
