# Cross-sells
Cross-sell items are similar to impulse purchases and appear with **up to 6** products on the shopping cart page, just before the customer begins the checkout process.
{% hint style="info" %}
For configurable products, the cross-sell products displayed will be the ones linked to the configurable **parent** product.
{% endhint %}
### Add cross-sell products
1. Open the product in edit mode.
2. Scroll down and expand the *Related Products, Up-Sells, and Cross-Sells* section.
3. Click Add Cross-Sell Products.
4. Use the filter controls to find the products that you want.
5. In the list, select the checkbox of any product you want to feature as a cross-sell product.
6. When complete, click Add Selected Products.
7. Save the product.
{% hint style="info" %}
**Caching Note**
The products will be updated on the front-end immediately after save as they are part of the ScandiPWA caching solution that will invalidate caching entries for the updated content. No cache flush or any other manual operations are necessary. Content will be visible after page refresh and a new cache entry will be stored.
