## Overview

The Cart Store provides a collection of selectors and methods to manage and retrieve cart-related data for WooCommerce Blocks. It offers functionality ranging from fetching cart details to managing customer interactions, such as applying coupons or updating shipping information.

## Usage

To utilize this store you will import the `CART_STORE_KEY` in any module referencing it. Assuming `@woocommerce/block-data` is registered as an external pointing to `wc.wcBlocksData` you can import the key via:

```js
const { CART_STORE_KEY } = window.wc.wcBlocksData;
```
