At dinner last night, I talked to a young author about her book and in particular her sales on Amazon. As was indicated in Enshittification, Amazon takes an enormous percentage of the sales price, in addition to fees to have a store. Amazon sales lose money. But the author feels she must be on Amazon for the exposure. An example month: sales on Amazon $75, author got $40, monthly fee for store $40. Fees go up with volume, so a vendor cannot ramp up sales to escape Amazon’s take by very much.
