# How to setup a Buy X Get X on the same Product (SKU)

${youtube}[How to setup a Buy X Get X on the same Product SKU](5ZA2-jxTcAM)
This guide explains how to set up a "Buy X, Get X" offer where the discounted or free item must be identical to the one the customer purchases (i.e., the same SKU).

### 1. Start Your BOGO Campaign

1. In the Kite app, begin a new promotion using the **Advanced Buy X, Get Y BOGO** option.
2. Give your campaign a name (e.g., `Same-SKU-Offer`).

### 2. Define the "X" Condition (What Customers Buy)

1. In the **'Product X'** section, select the products or collections that are eligible for this offer (e.g., the "Hydrogen collection").
2. Specify the quantity a customer needs to purchase to trigger the discount (e.g., `1`).

### 3. Set the "Y" Condition to Match "X"

1. In the **'Product Y'** section, select the special option **"same product SKU as 'Product X'"**. This is the key setting that ensures the offer only applies to identical items.
2. Specify the quantity the customer will get at a discount (e.g., `1`).

### 4. Set the Discount Value

* Choose your discount type and value. For a classic "Buy One, Get One Free" deal, set the discount to `100%`.

### 5. Configure Repetition (Optional)

* Set a limit for how many times this offer can be repeated in a single order. Setting a high number allows the deal to apply continuously (e.g., a customer buying 4 of the same item would get 2 of them for free).

### 6. Save the Promotion

* After configuring any additional eligibility rules, click **Save**.

### How It Works on Your Store

* If a customer adds two *different* products from the eligible "Hydrogen collection" to their cart, the discount will **not** apply.
* If the customer adds one of an eligible product, and then increases the quantity of that **same, identical product** to `2`, the discount will be applied to the second unit.
