Look at their budget. Most of their revenue comes from AWS. So their large AWS clients are their customers. The margins on the retailing e-commerce customers is slim and wasn't profitable on a cashflow basis until recent years. From a financial perspective, they're the people who are going to stock the items and take the risk for products where demand is uncertain. Once more data is collected about their sales, Amazon will use their scale to undercut their e-commerce selling partners. So they are important to their company logistics, just not to the bottom line.
