Out of the box, no. The Quantity Breaks app is designed to offer tiered pricing on the products purchased. However, if you're comfortable making changes to your store's theme, you can customize it to make this work.
The Quantity Breaks (standalone) app is no longer available for new installations. If you are currently using Quantity Breaks, you will be able to continue using the app on a grandfathered plan.
New requests for Quantity Breaks will be directed to Custom Pricing which has a Quantity Breaks plan available. For more information, please visit Custom Pricing Overview.
