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 (standalone), you will be able to continue using the app on a grandfathered plan.
Any new installs of the Quantity Break app will be redirected to Custom Pricing which has a Quantity Breaks plan available. For more information on Custom Pricing, please visit Custom Pricing: Information and Overview.
