Discount Codes & Rules gives you full control over discount codes. Generate thousands of unique codes in bulk or import from a CSV, or create a reusable code targeted at a customer segment using tags. Limit percentage or fixed-amount discounts to just one eligible item per order, a precision Shopify doesn't offer natively. Block codes automatically when restricted items are in the cart, like gift-with-purchase products. Great for large promotions and preventing bad combinations.
