Affiliate Disclosure

Blunder School is free to use — the trainer, the video library, the study paths, all of it. To help keep it that way, some links on this site are affiliate links.

Amazon: Blunder School is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate, we earn from qualifying purchases. When you buy a chess book through one of the links in our shop, we may earn a small commission — at absolutely no extra cost to you.

Merch: Blunder School t-shirts and gear in our shop are sold through our own print-on-demand store. Those aren't affiliate links — they're our products, and proceeds support the site directly.

What we don't do: we never recommend a book or product just because it pays a commission. Every book in the shop is a genuine, widely respected recommendation we'd make anyway. We also never charge for or accept payment for placement in the video library — videos are curated purely on educational quality.
