To preview your upsell(s) in your Shopify store, you can now add
?tabarnap_preview=true to any url where you have an upsell. For example:
This is useful when your store is live and driving good traffic and when you simply want to make some tests or making sure everything is fine.
To recap, the upsell can be previewed live, even when the upsell is in "draft mode". Such draft upsell is not visible for customers, but adding
?tabarnapp_preview=true parameter to your url will make it visible for the admin user (you, most probably, but also everybody who will add this param).
Tabarnapp's mission is to help you get the most of each visit on your Shopify store.
