How to use Shopify Scripts to create an upsell-only discount

Offering a discount of at least 10% on an upsell item increases its take rate by 14%. But how do you apply a discount to a product only when it’s added as an upsell?

‍

There are two ways to do this:

‍

1/ The old way: duplicate the product and set a product-level discount. Now you have two versions of the same product. When you have over 30 SKU’s this becomes cumbersome.

‍

2/ The new way: create a Shopify Script that only applies a discount when the item is added as an upsell. To do so, we target a specific variable this product receives when it’s added as an upsell.

‍

Here’s a guide on setting up your Shopify Scripts to achieve this.

‍

You’ll need:

‍

• Shopify Script Editor App (https://apps.shopify.com/script-editor)
• UpsellPlus app (https://apps.shopify.com/upsellpluscheckout)
• (Optional: Shopify Plus if you want to upsell in the checkout, which is what this guide outlines)
• ‍

Step 1: ​​Go to the official Shopify Script Editor App

(https://apps.shopify.com/script-editor)

Click ‘Create Script’ > Choose the type of script you’re adding. Here, we choose between a percentage (%) off a product or amount ($) off a product discount. Select your choice and click ‘Create Script’. Name your Script.

‍

Step 2: Add the code

Now we’ll add the following code:

If you’re not familiar with code, this does the following:

‍

IF the item added to the cart has “upsell_id” as a property

THEN apply a 10% discount and display the message ‘Upsell Discount’

‍

The “upsell_id” is added by our app, UpsellPlus, to all items that get upsold, so we can track upsell performance.

‍

‍

The key here is adding the 'if line_item.properties.has_key?("__upsell_id")'. This will look for any product that is added by UpsellPlus.

‍

Step 3: Choose your discount amount, percentage, or message

You can change the discount amount, percentage and message:

‍

Percentage discount: line_item.line_price * 0.90

Amount discount: Money.new(cents: 500)

Message: message: "Upsell Discount"

‍

Two examples:

A 10% discount:

‍

A $5 discount:

‍

‍

Note that you need to use a specific notation to get to $5 (500 cents, more on that here: https://help.shopify.com/en/manual/checkout-settings/script-editor/shopify-scripts#money)

‍

Result in checkout for both examples:

‍

‍

‍

‍

Step 4: Save and publish your script and test it on your live store

If you already have existing campaigns running with Shopify Scripts, you can add this script just below it.
