Quantity Engine helps merchants discount quantity breaks without managing discount codes by hand. Create tier rules for products or variants, preview results in the simulator, then activate to publish an automatic discount at checkout. Merchants can also set tiers from a product page and optionally show quantity breaks on the storefront with a theme block.

• Create quantity tier rules for products or individual variants
• Preview tier results with the built-in simulator before you go live
• Activate a rule to publish an automatic discount at checkout
