# Buy X Get Y The **Buy X Get Y** rule allows you to create **gift-oriented promotions** where customers receive **free products or discounted items** after purchasing specific products. With this rule type, you can define which products trigger the promotion by selecting: * Product categories * Product names * Variations * Product tags * Price ranges * Specific products Once the conditions are met, customers can receive a **free item or a discounted product** from the list you define.

### Count Quantity By The **Count quantity by** option determines how the system calculates the product quantity required to trigger the promotion.

* The **All together** option calculates the total quantity of all items in the cart, regardless of product type. It applies the bulk discount based on the combined total quantity. For example, 5 units of Product A and 3 of Product B would total 8 units, triggering the discount * The **Item quantity in each cart line** option calculates discounts based on the quantity of each product in separate cart lines. Each product's discount is applied independently. For example, 5 units of Product A and 3 units of Product B will receive discounts based on their individual quantities * The **Each single product/variable product** option treats each product variant (e.g., size, color) as separate items for quantity calculation. Discounts apply based on the quantity of each variant. For example, 3 units of "Small" and 4 units of "Medium" will receive separate discounts based on their individual quantities. ### Repeat Rule The **Repeat** option allows you to determine whether the promotion **can be applied multiple times** within the same cart. * **Enabled:** The rule repeats for every qualifying quantity. * **Disabled:** The promotion applies only **once per order**. ### Buy Products The **Buy Products** field allows you to define **which products customers must purchase** in order to trigger the promotion. You can select products based on: * Categories * Specific products * Tags * Variations * Price filters ### Get Products The **Get Products** field lets you define **which products customers receive as a free or discounted item**. These products will appear as the **eligible reward items** when the promotion conditions are met. ### Apply Mode The **Apply Mode** setting determines **which product from the Get Products list will receive the discount or free offer**. There are three options available:

* **Default:** Free/discount products will be selected in sequential order from the list. * **Cheapest one:** The product with the lowest price among the items in the **"Get Products"** list will be selected for a free item or discount. * **Most expensive one:** The product with the highest price among the items in the **"Get Products"** list will be selected for a free item or discount. #### Example 1: Buy 2 Accessories, Get 1 Free Item You are setting up a rule that allows customers to get 1 album, beanie, belt, or cap for free when they buy 2 items from the "Accessories" product category.
