First of all, customers have no reason to return normal futures, and shopping malls generally have no reason to return agreements. The transportation expenses incurred shall be borne by the customer. Personalized products should be informed to customers when they are sold, and they are not allowed to be returned. If the customer insists on returning the goods, he will calculate a return order and tell him that it is not cost-effective. Generally speaking, I won't make these demands again. If I insist on them, I will return the futures. If I don't return my dignity, I will calculate the freight. Whether you are a person or not, you will make money.
