DiscountQuantity

Defines a quantity threshold for discount eligibility or application. This simple object specifies the number of items required to trigger or calculate discount benefits.

For example, a "Buy 3, Get 1 Free" promotion would use DiscountQuantity to define the minimum purchase quantity of 3 items, or a bulk discount might specify quantity tiers like 10+ items for wholesale pricing.

The quantity value determines how discounts interact with cart contents, whether setting minimum purchase requirements or defining quantity-based discount calculations.
