Why are you defending Amazon's fees here so much? The costs they charge relate more to their monopoly on where people shop than their actual costs involved
It's just scary to think how much product quality suffers when these companies charge so much in fees. It's a race to the bottom to make any profit at all and they don't have much left to actually consider quality
The fees are broken out into line items. Shipping and inventory costs is a relatively small part. General marketplace fees are much higher. Have you ever sold on Amazon or done any research on this?
The general marketplace fees are the same whether you use FBA or not. Your original comment was complaining about FBA fees which are separate from the marketplace fees.
