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."
Set up the Upsell block your way.
Pick your offer logic
By tag (matching SKU type), by collection (all subscription add-ons), or by order value (upsell triggers above $50).
Choose the product
One product per offer block. Multiple offer blocks can stack — but limit to two for sanity.
Test the add-to-cart
The Add button adds without leaving checkout. Cart total updates inline.
-
How is this different from post-purchase upsells?
Post-purchase asks after they pay — lower friction but lower attach rate. Checkout upsell catches them at peak intent.
-
Can I show different upsells to different customers?
Yes. Use Checkout Rules or Conditional Visibility — different upsell by segment, country, cart contents, etc.
-
Does the upsell affect shipping?
Shopify recalculates shipping in real time when the upsell adds to the cart. No mid-cart surprises.
