可能是因为商家设置了唯一的配送方式,通常是商家自营或者平台代发货。
也有可能是因为该商品不支持选择配送方式,例如某些特殊商品(如大件商品、进口商品等)只能由平台统一配送。建议联系商家或平台客服咨询具体情况。
It may be because the merchant has set a unique delivery method, usually the merchant is self-operated or the platform is responsible for delivery.
It may also be because the product does not support the selection of delivery methods. For example, some special products (such as large items, imported products, etc.) can only be delivered by the platform. It is recommended to contact the merchant or the platform customer service for specific details.
Is there no customer service? Just ask the customer service and you will know. Any platform has customer service
