Yuko Extension (app embed) — required
Enabled under Theme editor → App embeds. Without it, nothing renders and offers show the Not Visible badge in the Offers list.App blocks (optional, product templates)
Add these in the theme editor when you want to position a widget manually instead of relying on auto-mount:
In theme-editor preview, blocks print diagnostic messages when they have
nothing to show (offer inactive, widget disabled, product not targeted) —
live shoppers never see these.
The Bundle Builder page
Build Your Own Box doesn’t use a product-page block for its main experience — the app auto-creates an Online Store page per offer and renders the builder there. See Build Your Own Box.Behind the scenes (no setup needed)
Discounts and bundle pricing are applied by Shopify Functions installed with the app — an automatic discount function (“Yuko Discounts”) plus bundle/cart-transform functions that merge bundle items in the cart. There are no discount codes, and merchants never configure these directly.Need help?
