how to sell books through amazon is straightforward whether you’re an author or reseller. Authors can use Kindle Direct Publishing for eBooks and print-on-demand. Resellers list physical books via ISBN, describe condition, and ship themselves or use FBA. Rare, collectible, or textbook markets offer good margins. Use keyword-optimized titles, competitive pricing, and great condition descriptions. Customer reviews and seller rating also influence success. Selling books can be a sustainable, low-investment entry into online commerce.
