Steply Volume Discounts lets you run quantity breaks without editing your products. Add tiers with a minimum quantity and a percentage discount, and pick the products, variants or collections they cover. Shopify applies the highest tier reached at checkout, counting the chosen variants of a product together. An optional product page block lists the tiers for the selected variant, and its buttons set the quantity. The app shows whether each discount is live at checkout.

• Set several quantity tiers, each with its own percentage discount
• Target chosen products, only some of their variants, collections or all products
• Show a tier table on the product page that follows the selected variant
• Shopify applies the discount at checkout, so your products are never edited
• Choose which product, order and shipping discounts your tiers combine with
