How do I only discount a product when it's added as an upsell with Script Editor?

When you want a discount to apply to a product only when it's added as an upsell, you can use a simple Shopify Script.

Go to your Shopify Script Editor app and add the following script for

A percentage discount:

Input.cart.line_items.each do |line_item|
if line_item.properties.has_key?("__upsell_id") and line_item.properties["__upsell_id"].include? "e766cbff-060d-4ed7-9797-ccb9d2bdcf1a"
line_item.change_line_price(line_item.line_price * 0.8, message: "Flash Sale")
end
end
Output.cart = Input.cart

A discount amount:

Input.cart.line_items.each do |line_item|
if line_item.properties.has_key?("__upsell_id") and line_item.properties["__upsell_id"].include? "e766cbff-060d-4ed7-9797-ccb9d2bdcf1a"
line_item.change_line_price(line_item.line_price - Money.derived_from_presentment(customer_cents: 500), message: "Flash Sale"))
end
end
Output.cart = Input.cart

There are three parameters you can adjust. They are highlighted in green.

The discount % or discount $

Example of a 20% discount

line_item.change_line_price(line_item.line_price * 0.8)

Example of a $5 discount

line_item.change_line_price(line_item.line_price - Money.derived_from_presentment(customer_cents: 500))

The discount code displayed to the customers

Example of a discount code saying: Flash Sale

line_item.change_line_price(line_item.line_price * 0.8), message: "Flash Sale"

The specific upsell offer you're targeting with this script

Example of a discount targeting upsell offer with offer ID: e766cbff-060d-4ed7-9797-ccb9d2bdcf1a

if line_item.properties.has_key?("__upsell_id") && line_item.properties["__upsell_id"].include? "e766cbff-060d-4ed7-9797-ccb9d2bdcf1a"

You can find the offer ID in the UpsellPlus app. Go to your upsell offer. At the top you will see the offer ID displayed.



Copy and paste it into the script.

Save and publish your script in the Script Editor app.****
