DealMint

Quantity breaks and sales that never sell a product below the margin you choose.

• Margin floor at checkout. Each product's discount is capped so its price stays above cost plus your minimum margin. The order always goes through.
• Margin check before launch. See which products get the full discount, a reduced one, or none, before a campaign goes live.
• Costs stay in sync. Uses “Cost per item” from Shopify and updates when it changes.

Install DealMint from the Shopify App Store.
