# Component: Block Related Purchase Modal

#### **Purpose**

Use this Enforcement Component to block purchases related to a product a customer already owns. For example, if you want someone who already has Digital + Print to not be able to buy Digital, then use this component.

Another example is if a customer has your Gold package, they should not be able to buy an add-on already included in Gold.

### Important considerations

* This component will only work to block purchases of products specified in the **Related Products to Block Purchase** attribute of a Limio Product the user owns.
* If you want to the block to apply both ways (owning product A prevents purchasing product B and vice versa) then the attribute needs to be configured on both products.
* To display this Dialog, the checkout must be authenticated.
