Affiliate disclosure

As an Amazon Associate I earn from qualifying purchases. This page explains what that means on this site.

Which links are affiliate links

Every button that says "Check the price on Amazon", and every link to Amazon.com on this site, carries our Amazon Associates tag. If you buy through one of these links, Amazon pays us a commission. The price you pay is the same as without the link.

What it never changes

The order of a comparison follows the six scores described in how we compare. A tree does not move up because its commission is higher, and no maker or seller pays to appear on the site.

Why we show no prices

Prices on Amazon.com change often, sometimes several times a day. Rather than show a figure that may already be out of date, we send you to Amazon, where the current price is shown.

This disclosure follows the Federal Trade Commission's guidance on endorsements. Questions are welcome on our contact page.
