# Manage Add-On Products

To apply an extra charge to an option, the app links it to an **add-on product**.\
You can:

* Generate a new add-on product in the app automatically.
* Use an existing product from your Shopify store.

When the option is selected, the add-on product’s price is added to the main product’s subtotal.

{% endstep %}

{% step %}
To change the price, simply edit the product directly in your **Shopify admin**, just like any regular product.

{% endstepper %}

#### 🧾 Cart Behavior:

* When a customer selects an option with an add-on product, **both** the main product and the add-on will appear in the **cart**.
