# Discounts

> Display discounts in a Shoplazza Theme with the discount_applications and line_item objects, covering cart, checkout, and order level discounts.

Discounts can be applied at the line item level, or the cart, checkout, or order level. This means that they apply directly to specific line items, or apply to the cart or order as a whole.

In this tutorial, you'll learn how to display discounts in your theme.

## Requirements

You've created a [cart template](../../architecture/templates/cart) or a [order](/docs/theme/references/liquid/objects/order) template.

## Resources

To display discounts in your theme, you'll use the following:

* [The discount\_applications object](./discounts#the-discount_applications-object)
* [The line\_item object](./discounts#the-line_item-object)
* [The spz-cart component](https://lessjs.shoplazza.com/latest/components/spz-cart/)

### The `discount_applications` object

The [discount\_application object](/docs/theme/references/liquid/objects/discount_application) registers discounts at the cart, checkout, or order level. Depending on where you're implementing your discount display, you'll access the relevant discount applications through the associated parent object:

* For the [cart](../../architecture/templates/cart) template
  * [cart.discount\_applications](/docs/theme/references/liquid/objects/cart)
* For the [order](/docs/theme/references/liquid/objects/order) template
  * [order.order\_info.discount\_applications](/docs/theme/references/liquid/objects/order_info)

### The `line_item` object

To complete the price display, you need to use price and discount attributes of the [line\_item](/docs/theme/references/liquid/objects/line_item) object, including:

* [original\_line\_price](/docs/theme/references/liquid/objects/line_item)
* [final\_price](/docs/theme/references/liquid/objects/line_item)
* [final\_line\_price](/docs/theme/references/liquid/objects/line_item)

## Implementing discount displays

Because discounts can apply to line items or to the cart or order as a whole, you should display discount information in two places:

* [With individual line items](./discounts#line-item-discounts)
* [With the total summary](./discounts#cart-discounts)

The examples in this tutorial use the [cart template](../../architecture/templates/cart#usage).

## Line item discounts

If a discount applies to specific line items, then it should be displayed with those items. To display discounts with line items, you need to include the following in your display:

* [The line item price](./discounts#line-item-price)
* [The line item discount](./discounts#line-item-discounts-1)

### Line item price

If a discount has been applied to a line item, then you should show the new discounted price. Each of these can be accessed with the following attributes of the Liquid [line\_item object](/docs/theme/references/liquid/objects/line_item):

* [final\_price](/docs/theme/references/liquid/objects/line_item)
* [final\_line\_price](/docs/theme/references/liquid/objects/line_item)

### Line item discounts

If a discount has been applied to a line item, then you should show each discount that's applied, with its associated discount amount, or discount icon.

```liquid title="Example"
<spz-cart layout="container">
  <template>
    <div>
      <div spz-for="line_item in data.line_items">
        <div spz-for="discount_application in line_item.discount_applications">
          <div>
            <spz-img
              spz-if="${!!discount_application.icon}"
              src="${discount_application.icon}"
              layout="fixed"
              width="16"
              height="16"
            ></spz-img>
            <span>${discount_application.title}</span>
          </div>
          <span spz-if="${discount_application.discount_amount > 0 || discount_application.amount > 0}">
            (-<spz-currency style="display: inline-block;" layout="container" value="${discount_application.discount_amount || discount_application.amount}"></spz-currency>)
          </span>
        </div>
      </div>
    </div>
  </template>
</spz-cart>
```

## Cart discounts

The line price is the line item total after line item discounts have been applied, and the total is the cart after cart discounts have been applied.

```liquid title="Example"
<spz-cart layout="container">
  <template>
    <div>
      <div>Line price:  <spz-currency layout="container" value="${data.line_price}" style="display: inline-block;"></spz-currency></div>

      <div spz-if="${data.total_discount > 0}">
        Discount: -<spz-currency layout="container" value="${data.total_discount}" style="display: inline-block;"></spz-currency>
      </div>

      <div>
        Total: <spz-currency layout="container" value="${data.total_price}" style="display: inline-block;"></spz-currency>
      </div>
    </div>
  </template>
</spz-cart>
```
