# Block discounts shopify checkout extension

Firmhouse provides a Shopify Checkout Extension that blocks any checkouts containing subscription plans from allowing a discount to be active or a discount code to be entered. This ensures that discounts intended only for one-time purchases cannot be applied to subscription products.

When customers pay for their subscriptions using local payment methods like Bancontact and iDEAL | Wero, Firmhouse uses special selling plans. However, Shopify doesn't recognize these special plans as subscriptions, which means discounts meant only for one-time purchases can still be applied to these subscriptions. The checkout extension prevents this by validating the cart at checkout.

> **Warning:** This rule blocks checkout if any discount is applied to a subscription product, or if an order-level discount is applied while a subscription product is in the cart. If you plan to allow discounts on certain subscription products, do not enable this rule, as it will block those as well.

## How to set it up

### Steps

1. Open your [Shopify admin](https://admin.shopify.com/settings/checkout) and go to **Settings > Checkout**
2. Scroll to the **Checkout rules** section
3. Click **Add rule** and select **"Disallow all discounts for subscription products"** under **Firmhouse**
4. Uncheck **"Allow all customers to complete checkout"** to ensure discounts won't slip through even if there's an error
5. Click **Save**, then click **Turn on** in the top right corner

Now, discounts will be blocked for all subscription products while still being available for one-time purchases. Your customers will see an error message when they try to apply a discount on a cart with subscription products.
