DiscountOS lets you run different discounts for different markets from one place. Set up product, order, bundle, BOGO, tiered, volume, and shipping discounts that change based on Shopify Markets regions. Build precise targeting with AND/OR logic using customer tags, B2B status, login state, or purchase history. Create both automatic discounts and discount codes that stack at checkout. Schedule campaigns and set usage limits to prevent discount abuse. Works with subscriptions and onetime purchase
