The example demonstrates how you can apply a coupon code to receive a discount on your [order](https://docs.kentico.com/k81/e-commerce-features/configuring-and-managing-your-store/orders.md). The 10% discount has no time limit, and is available to all your [customers](https://docs.kentico.com/k81/e-commerce-features/configuring-and-managing-your-store/customers.md). It uses a coupon code that the customers can apply up to 10 times to receive the discount. The coupon code is applied while editing an existing order in the administration interface, and while shopping on the live site.

The example uses the sample _E-commerce Site_.

## Adding an order discount

First, you need to add a new order discount.

1. Open the **Order discounts** application.
2. Click **New order discount**.         

   - The system opens a page where you can specify the discount properties.
3. Enter the following values for the discount's properties:                

   - **Name**: Sale
   - **Enabled**: Yes (checked)
   - **Discount**: Percentage
   - **Amount**: 10
   - **The customer must enter a coupon code to receive the discount**: Yes (checked)
4. Click **Save**.

The system opens the **Coupons** tab of the newly added time-unlimited order discount, available to all customers. Now you can add a coupon to the discount.
