We are listed in the Book category My Query is about the shipping fee Structure.

Currently, we have opted for Self Ship wherein Amazon is charging a commission on shipping costs too.
Suppose, If we opt for the Easy ship module apart from the weightage charges are there any Additional Fees charged for the product sold such as a Referral fee or Commission?

also please let me know where can I find Our detailed business reports in terms of “EBIT” and Net Earnings.
