# Upcart x Wide Bundles – Quantity Breaks

> This article explains how to resolve add-to-cart issues that can occur when using Wide Bundles with Upcart for quantity break offers.

# Overview

When using Wide Bundles and Upcart together, you may notice that the cart does not open correctly after a customer adds an item. This usually happens when the **Add-to-Cart Redirection** setting in Wide Bundles is not configured to work with Upcart.

## How to Fix It

Follow these steps to resolve the issue:

1. Open your **Wide Bundles** settings.
2. Locate the option for **Add-to-Cart Redirection**.
3. Set this option to **Side Cart**.

Setting it to **Side Cart** ensures that your cart opens correctly in Upcart after a customer adds a product to their cart:
