# How to setup Advanced tiered discount?

${youtube}[How to setup Advanced tiered discount?](Fh3kf-cRIP0)
This guide explains how to create a "Buy More, Save More" offer where customers unlock higher discount percentages (e.g., 10% off 2 items, 20% off 3 items) based on the quantity of eligible products in their cart.
### Step-by-Step Configuration
**1. Basic Setup & Product Selection**
* **Name:** Give your campaign a clear internal name (e.g., "Tiered CD Test").
* **Discountable Products:** Choose which items qualify for the discount.
* **Options:** All Products, Specific Collections, Product Tags, or even Subscription Products.
* Note: In this example, we select **"All Products"** to create a store-wide volume discount.
**2. Define Tiers & Triggers**
* **Tiers Based On:** Select **"Quantity of all selected products"**. This means Kite counts the total number of eligible items in the cart to determine which tier the customer has reached.
* **Setting the Tiers:**
    * **Tier 1:** Set Quantity to **2**. Set Discount to **10%** (Percentage).
    * **Tier 2:** Set Quantity to **3**. Set Discount to **20%**.
    * Optional: Add a "Title" for each tier (e.g., "Buy 2 get 10% Off") to display on the widget.
    * Other Modes: You can also use Fixed Amounts ($ off) or Fixed Prices (e.g., "Buy 3 for $50 total").
**3. Advanced Limits & Sorting (Optional)**
* **Max Items to Discount:** Determine how many items in the cart actually receive the discount.
* **Leave Empty (Default):** The discount applies to **every** eligible item in the cart once the tier is reached.
* **Set a Limit:** Use this if you only want to discount a specific number of items (e.g., "Discount the first 5 items only").
* **Sorting Strategy:** If you set a limit above, you must choose which products get the discount:
* **Least Expensive:** Good for protecting margins (e.g., "Buy 3, get 20% off the cheapest item").
* **Most Expensive:** More aggressive offer (e.g., "Get 20% off your most expensive item").
**4. Save & Test**
* **Eligibility:** Optionally restrict this to specific Markets or Customer Tags (e.g., "Wholesale Customers Only").
* **Validation:** Save the campaign and test on your storefront:
    * **1 Item:** Full Price.
    * **2 Items:** 10% applied automatically.
    * **3+ Items:** 20% applied automatically.
### Technical Notes & Limitations
> **Stacking Logic:** Since this is a Product Discount, it typically does not stack with other Product Discounts (like a specific "20% off T-Shirts" code) unless you enable "Combinations" in the settings.
> **Subscriptions:** If targeting subscription products, the discount will apply based on your selling plan configuration (often applying to the initial checkout order).
### Troubleshooting Checklist
* **Discount not upgrading?** Ensure the customer is adding items from the **Discountable Products** list. If they add 2 eligible items and 1 non-eligible item, the count is still only "2".
* **Discount applied to wrong items?** Check your **Sorting Strategy** (Cheapest vs. Most Expensive) if you set a limit on the "Max Items to Discount."
* **Widget not updating?** If you are using a Side Cart, ensure your theme allows Kite to detect cart changes, or try refreshing the page to see if the discount applies.
