Affiliate disclosure
The tools are free. Here's how the site can still pay for itself.
Some outbound links on this site may be affiliate links: if you click one and sign up for or buy something, we may earn a commission. It costs you nothing extra — the price you pay is the same either way.
Our rules for affiliate links
- Tools are never affected. What a checker reports, what a calculator computes, and what a guide recommends is decided on the merits — never by whether a commission is attached.
- We only link to services relevant to digital and print-on-demand sellers — the kind of thing we would mention anyway.
- Everything stays free. Affiliate income is what lets the tools remain free, private and signup-free.
Current status
As of 28 July 2026, affiliate partnerships are being established; where a live affiliate link appears in a guide or tool page, it is covered by this disclosure. This page will be kept current as partnerships change.
Questions about any of this are answered in plain terms on the about page, alongside our accuracy standards.
