Create percentage or fixed-amount quantity tiers for one product, a collection, or your full catalog. Display buy-more-save-more breaks near the buy button, highlight the active tier as quantities change, and apply the discount automatically with Shopify Functions. Quantities across variants of the same product combine toward the same tier. Product rules override collection rules, which override catalog-wide rules. Configuration loads from Shopify metafields without collecting customer data.

• Show quantity breaks on product pages and highlight the active tier
• Apply percentage or fixed-unit discounts automatically at checkout
