Bracket pricing is a price schedule based on the number of cases that a retailer orders. The greater the quantity ordered, the lower the price per case. Bracket pricing is also termed as a volume or quantity discount. The most common quantity discounts exist when a buyer places an order that exceeds a certain minimum level. While quantity discounts are used by marketers to increase higher purchase levels, the rational for using these often rests in the cost of product shipment. Shipping costs tend to decrease per item shipped.
