Print-on-Demand & KDP playbook

Reddit's Merch by Amazon tier-up threads mix real royalty-group rules with unofficial folklore. Here is which claims Amazon actually documents and which are guesswork.

French residents can apply to Merch on Demand. The real gate is Amazon's invitation, then a W-8BEN tax interview and a bank payout. Eligibility, withholding math and backups.

KDP Spy isn't sold separately — it's the Chrome extension inside Book Bolt Pro ($23.99/mo) and Premium ($35.99/mo). Here's what each actually includes.

There's no number of low content books that guarantees income. Here's the real per-copy royalty math, and why sales-per-title can't be predicted.

Expanded Distribution puts your KDP paperback in front of bookstores and libraries for free, but pays a flat 40% royalty. Here is the real math.
