Which of the following refers to a price reduction based on the size of order?

The price reduction based on the size of an order is called a "Trader Discount." A trader discount is a reduction in the price of goods or services that a buyer receives based on the quantity of the goods or services purchased. The discount is usually given as a percentage of the total purchase price, and the larger the order, the greater the discount. The purpose of a trader discount is to incentivize customers to purchase larger quantities of goods or services, which can benefit both the buyer and the seller. For the buyer, the discount can result in lower per-unit costs, while the seller can benefit from increased sales volume and revenue. In summary, a trader discount is a price reduction that a buyer receives based on the quantity of goods or services purchased. The larger the order, the greater the discount, and the purpose of the discount is to incentivize customers to purchase larger quantities of goods or services.
