Affiliate Disclosure

Last updated: October 12, 2026

Ready Useful may earn a commission when you make a qualifying purchase through a paid affiliate link on this site. This commission supports the site and its free tools.

How we identify paid links

Paid purchase links are accompanied by a notice explaining that we may earn a commission. This disclosure page provides more detail; the notice beside the purchase link identifies the commercial relationship where you make your decision.

No paid affiliate purchase links are currently configured on the site. Current merchant purchase links are ordinary links that do not earn us an affiliate commission. Applying to an affiliate program does not by itself turn a link into a paid link.

What a commission means

A merchant or affiliate network may attribute your purchase to our referral and pay us under its program terms. Qualifying purchases, attribution windows, exclusions, and commission rates vary by program. The merchant sets prices, handles checkout and payment, and is responsible for shipping, returns, and customer service.

Sources and product limitations

Our guides distinguish manufacturer references, supplier claims, and community reports. A purchase link or affiliate relationship does not establish compatibility, product quality, or first-hand testing. Check the evidence and limitations on the relevant tool page and verify the exact product before ordering.

For Filter Passport, we organize published replacement references and dimensions; we have not physically tested the listed filters. Print Fit Planner provides geometric estimates rather than a guarantee of print quality. The Octatrack Parts Guide labels repair evidence and uncertainties; a listed part is not a guarantee of fit.

Other commercial relationships

If we publish sponsored content or receive free products or other benefits connected to a recommendation, we will identify that relationship with the relevant content.

Privacy and updates

Affiliate networks and merchants may use referral tracking when you follow a paid link. Read our Privacy Policy and the destination site's policies for more information.

We will update this disclosure as our commercial practices change.
