Prepare a small test
Write down unit cost, shipping, tax treatment and a target contribution for one product. Pick two plausible basket quantities, not arbitrary thresholds.
Work through the task
Configure a CartLift tier for the selected product and preview the product and cart views. Add quantities just below, at and above each threshold. Check the actual checkout discount and whether another promotion can combine with it.
Check the result
Calculate contribution at each tier and check a return or partial cancellation scenario in a test store. Keep screenshots of the offer customers saw and the checkout total.
Current limits
The registry has no verified public CartLift listing. Shopify behavior depends on the installed app and store configuration; test in a development store before promotion.
