Show quantity breaks on your product pages and let Shopify apply the discount at checkout. Set each tier as a percentage, an amount off, or a target amount per item. Before you publish, the app previews every tier exactly as a buyer will see it, rounding included. A tier that could never apply is flagged before it goes live. Offers do not combine with other discounts unless you say so, so a buyer never gets two discounts on the same item by accident. Buyers see your tiers in their language.
