+### Free products: Add same items as ordered
+
+**Free products: Add same items as ordered** calculates the number of free units based on items in the cart, and applies them to the products selected in **Discounted products**.
+
+The free units are calculated per matching item in the cart, but they are not automatically assigned to those same items.
+
+Use this option when you want to calculate free units from cart items while controlling exactly which products or collections receive the discount.
+
+<Warning>
+Be careful when using **Multiply discount by each bundle added** with broad product collections or high quantities — the number of free products can increase quickly.

+**Example:**

+- **Bundled items:** Collection "T-Shirts", minimum quantity = 1  
+- **Discount type:** Free products → Add same items as ordered  
+- **Free units:** 1  
+- **Discounted products:** Collection "Socks"  
+- **Multiply discount by each bundle added**
+
+**Result**:
+
+A customer who adds 3 T-shirts to the cart gets 3 socks discounted as free, as long as **Maximum number of eligible bundles** is set to at least 3.

 ### Upgrade bonus: Replace order items
 
 **Upgrade bonus: Replace order items** replaces existing products with upgraded ones. The multiplication applies to both the added and removed items.
