# Shopping cart

Learn how to define an audience based on the shopping cart.

The [`cart`](/reference/cql/context#shopping) variable provides information about the user's shopping experience on your online store. It includes details such as the stage of the process, items in the cart, the total amount, and more.

For example, to create an audience of users who have started the checkout process, but have not yet completed it, you can use:

```cql
cart's stage is "checkout"
```

If you want to focus on users with specific items in the cart, you can use a quantifier:

```cql
some item in cart's items satisfies item's name matches "t-shirt"
```

Another typical use case is to display messages or special offers based on the shopping cart state. Suppose you want to offer users free shipping on orders over `100 by displaying a message like "Add `20 more to get free shipping". Then, you can use:

```cql
cart's subtotal is less than 100
```

You can even use the discount coupon as a condition:

```cql
cart's coupon is "new-year"
```

This can be useful if you need to give detailed instructions about the coupon rules, such as displaying a message like "This is a one-time coupon for new users only".
