We're introducing a new prerequisite_quantity_range parameter on PriceRule!
Help merchants move inventory with discounts that require a minimum quantity of items. For example, you can now create 20% off on products from specific collections when customer buys 3 items or more. This new property can be used with all discount types: percentage, fixed amount or free shipping discounts.
See more information the PriceRule API reference documentation.
As always, feel free to reply here with any questions or concerns!
