Who is cheaper, discount storage or temporary storage?

Discount warehousing. Discount warehousing is a chain store formed by selecting more popular and practical goods from the goods operated by comprehensive large supermarkets, reducing and narrowing the price gap and unifying the commodity level of various departments. Temporary storage refers to the goods (food) that are in stock and are about to expire, and the general merchants will take them out for promotion. The discount store is a manufacturer, and the manufacturer sells it directly to the shopping center, and the temporary store is a middleman. Someone else bought the temporary food from the manufacturer, so it is cheaper to store it at a discount.
