+### 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.
