The Checkout Ninja tag only marks the block in this preview — it never appears in your live checkout.
"Fantastic app, highly recommended. We've been using it for years — a long list of checkout customisations suited to our store. A must-have for all your Shopify checkout needs."
How to add Featured Upsell to Shopify checkout
Install Checkout Ninja from the Shopify App Store, open the checkout editor, and drag the Featured Upsell block into the section where you want it. Then configure it in three steps. No theme code, no checkout.liquid, and it survives every Shopify update because it runs on Checkout Extensibility.
Choose the product source
Hand-pick a custom product, or let Shopify choose — Related Products and Complementary Products both feed the block, and the top recommendation gets featured.
Set the copy and pricing
Add a heading and supporting line above the product. Compare-at pricing renders automatically as a strikethrough plus a “Save 12%” line.
Decide the out-of-stock behaviour
When the featured product is unavailable, either show an out-of-stock label or roll to the next available product. No dead offers.
-
How is this different from the standard Upsell block?
Upsell is compact and works well stacked. Featured Upsell commits the full block width to one product — large image, full details, prominent Add. Use it when one offer deserves the whole space.
-
Can customers pick a variant?
Yes. The variant selector appears automatically for products with more than one variant, and sold-out options are greyed out rather than hidden.
-
What happens if the featured product sells out?
Your choice. Show an out-of-stock label, or have the block automatically feature the next available product from the recommendation set.
