Partner Disclosure

This site is free to use. This page explains how it earns money and how we keep that separate from the numbers.

How The Site Earns Money

The site earns money from display advertising, and may earn a commission if you buy a product through a partner link. A link of that kind is always marked.

You pay the same price whether or not you use a partner link.

Independence

  • Calculations come from one engine and are not changed by any advertiser or partner.
  • Rules come from official sources, not from partners.
  • A partner cannot pay to be mentioned in a guide.
