The principle underlying quantity discounts is that increased purchase amounts lead to decreased per-unit costs. This practice is rooted in economies of scale, where the cost of production or procurement often decreases as the quantity of goods purchased increases. When a buyer commits to purchasing a larger quantity, the supplier is typically able to reduce the per-unit price due to lower costs associated with production efficiency, shipping, and packaging.

This pricing strategy benefits both the seller and the buyer; the seller increases sales volume and may streamline operations, while the buyer enjoys a lower total cost for a larger quantity of the product. Thus, the rationale of offering discounts is to incentivize buyers to purchase in bulk, which helps clear inventory and can lead to long-term customer relationships.

While loyalty rewards, seasonal demands, and competitive pricing strategies play significant roles in marketing and pricing, they do not directly address the systemic economic principle that ties increased purchase amounts to reduced per-unit costs.
