How can I let a shopper upgrade from a cart product to an upsell product that's shown?

If you're looking to add a true upsell to your checkout, you're in the right place! Head over to our demo store. When you add 2 or 6 cookies to cart, you'll see a true upsell to a larger size, 12 cookies. Here's a video if you'd rather just watch it in action.

Overview

UpsellPlus allows shoppers to seamlessly upgrade an item in their cart to a higher-value upsell product. This helps increase average order value while offering a better product experience.

Step-by-Step Guide

Log in to Shopify Admin

Open the UpsellPlus App
Go to Apps in the lefthand menu
Click UpsellPlus from the list of installed apps

Create a checkout upsell
Click Create Offer or edit an existing one
Select the product you want customers to upgrade from (current cart product)
