What is the ruling on a company representative distributing milk or newspapers to shops and returning unsold items to the company?

Question:
Honorable Shaykh, may Allah grant you success. He says: Some commercial shops that sell milk, magazines, or newspapers impose a condition on the companies that supply these goods that if they are not sold at these shops, the company representative will take them back. So, are they sinful for this agreement? This

Answer:
The form of it is that you are a broker for them; you sell the magazines and newspapers for them, and they give you a commission on the sale. But if you say, "I will buy from you what has not been sold," then what has not been sold is sold to you, and what has not been sold is what you take back; this is not valid. But if you say, "I will sell to you; I will sell your newspapers, your magazines, your milk, and your milk, and you take back what remains," because this is not a sale; this is considered being a broker for the company. They give him his fee for what he sold, and what he did not sell remains their property.
