Coloring books
Printed on demand through Amazon KDP
Themed books with real care in every page, not generic volume 3s. Each launch gets a write-up: cost, price, royalties, and what the ads did.
First book in progressSelling on Amazon without a warehouse, in public.
I'm Sean, and I build e-commerce and fulfillment systems for a living. Here I'm testing three ways to sell on Amazon without holding inventory: coloring books, print-on-demand shirts, and affiliate picks. I'll publish what each one actually earns.
Three experiments, no inventory
Each one runs for six months. At the end I'll keep whatever earns the most per hour and drop the rest.
Print-on-demand shirts
Through Amazon Merch on Demand
Designs that match the book themes, so each audience can find both. Amazon prints, ships and handles returns.
Applying to the programAffiliate picks
Through Amazon Associates
Only the tools and gear I actually use to run these experiments, each with a note on why. No roundups of things I haven't touched.
