Set up volume discounts like "10% off for 2+" or "20% off for 5+" in a few clicks. Pick products, set quantity tiers, and discounts apply automatically at cart and checkout — no coupon codes. Variants (sizes, colors) combine toward the total, or target specific variants precisely. Overlapping rules are auto-detected. Built on Shopify Functions — ideal when migrating from Script Editor. Setup takes ~60 seconds; start free, Pro adds a 7-day trial.
