In what way does Amazon know the backend margins that any other store wouldn’t? They don’t. Amazon isn’t being asked to produce a product for a vendor then taking that and selling it themselves, that would be wrong. This is Amazon doing exactly what other stores do, seeing what sells well and making their own version.
