Frequently Asked Questions

Does this include every Amazon fee?+
Not necessarily. Category-specific fees, prep, long-term storage, coupons, and VAT can still change the final payout.
Why include PPC and returns?+
Because many Amazon listings look profitable before ads and returns, then thin out quickly once real operating costs are included.
