FBA is not a fairy tale and not a crime. It is a crowded marketplace with a landlord that can change the rent.
People do make money sending goods into Amazon. They also tie up cash, eat unsold stock, and wake up to policy emails. Calling that passive income is the part we reject.
Skip the guru bundle. If you still want the work, read Amazon’s own fee pages until you can price a unit without a YouTube overlay. Then decide whether you wanted a warehouse job with extra steps.
