Upsell where the customer is already buying
When a customer opens their cart, they've already committed. In-Cart Upsell uses that moment to suggest one or two complementary items they'd genuinely want.
Combine with a small bundle discount and you'll see attach rates north of 20% on well-matched offers.
- Works in both cart drawer and full cart page
- Live total update as items are added
- Optional bundle discount via Shopify Functions
