You will be able to create tiered discounts for different ranges of units added to your Cart. This will apply to ALL products; there are no exceptions to any product added to the Cart. Please CLICK HERE to view a video showing the functionality.
Once you entered into your Admin Panel, select Configure Site on the left hand side and scroll to the very bottom. This is where you would be able to create the Unit Range, apply the Discounts, and manage the already created tiers.
