Todos los vendedores de Amazon.com deben pagar tarifas por referencia, que varían según el listado de productos, además de las tarifas del plan de venta.

This statement is true. All sellers on Amazon.com are required to pay referral fees, which are a percentage of the product's selling price. These fees vary depending on the product category. In addition to referral fees, sellers must also pay for a selling plan, which can be either individual or professional, each with its own associated costs. These two types of fees (referral fees and selling plan fees) are fundamental components of selling on Amazon.
