In short
- The referral fee is the one everyone knows and rarely the one that hurts.
- Storage and returns are where margin quietly disappears.
- You cannot price for Amazon until you have counted all of it.
What comes out, and in what order?
Referral fee, fulfilment, storage, returns processing, then advertising. Each one is small and they are not small together.
Most brands price for the referral fee and get caught by everything after it.
What can you actually change?
Packaging size, return rate and which products you back. The fee schedule is not negotiable.
