The problem it solves

Shoppers who skipped the pack on the product page often take it in the cart once they see the exact saving.

How it works

  • Detects a single item that is eligible for your pack offer.
  • Shows the saving for adding one more.
  • Uses the same Shopify Discount Function, so the checkout total matches.

How to add cart upgrade to a pack to your Shopify store

  1. Set up Quantity packs first.
  2. Turn on the "CartLift cart upgrade" embed.
