Graduated Unit Discount lets merchants create automatic product discounts based on the total quantity in a cart. Merchants set quantity tiers with a chosen discount rate while applying the discount to one unit only. They can choose the cheapest eligible product or the product most recently added to the cart. The app updates the selected discounted item as the cart changes.

• Create quantity tiers for one-unit automatic discounts.
• Choose the cheapest or most recently added eligible product.
• Apply the highest reached tier as cart quantity changes.
• Manage discount status and tier settings in the Shopify admin.
