¿Cuáles de las siguientes tarifas deben pagar los vendedores y se incluyen en el costo total de poner en marcha cupones?

The correct answer is "Comisiones de canje" (redemption fees). When sellers offer coupons on Amazon, they incur a small fee for each coupon redeemed by a customer. This fee contributes to the overall cost of running a coupon promotion. "Tarifas de gestión logística" (fulfillment fees) are associated with Amazon's fulfillment services (FBA), not directly with coupon promotions. While sellers using FBA pay these fees, they are separate from the specific costs of offering coupons. "No se incluyen tarifas" (no fees are included) is incorrect because coupon redemptions do incur a charge.
