Add theme blocks (Bought Together, Add-ons, Cart Page)

Some placements render as theme blocks you add to a specific template, so you control exactly where they appear.

Product page: Bought Together & Add-ons

1. In the theme editor, open your product template.
2. Click Add block in the section where you want the offer to appear.
3. Add UpsellEngine — Frequently Bought Together and/or UpsellEngine — Product Add-ons. Place Add-ons just above Add to Cart for best visibility.
4. Save.

See Frequently Bought Together and Product Add-ons for what each does.

Cart page

1. Open your cart template in the theme editor.
2. Add block → UpsellEngine — Cart Page.
3. Save.

Note: Theme blocks work on any Shopify plan — no Shopify Plus required. If a block is added but empty, the offer's trigger may not match the current product, or AI recommendations may still be generating; see Offer isn't showing.
