Para ofrecer un descuento exclusivo de Prime, el precio con descuento debe superar al precio más bajo de compra de los clientes para el producto en los últimos 30 días.

This statement is true. To qualify for an exclusive Prime discount, the discounted price must be lower than the product's lowest customer purchase price over the past 30 days. This rule ensures that Prime exclusive discounts offer genuine value to customers by guaranteeing a price that is genuinely better than recent historical lows. If the discounted price were higher or equal to the recent lowest price, it would not be considered an exclusive benefit for Prime members.
