ADU: Automatic Discounts is one of the best free discount automation apps for Shopify in 2025. It offers tiered discounts, free gifts, BOGO deals, and automatic upsells with a freemium pricing model. Merchants appreciate its ability to apply percentage discounts to the highest-priced item in cart, manage multiple promotions, and provide responsive customer support with personalized assistance like video tutorials and direct code implementation.
Free alternatives to ADU include Kaching Bundles Quantity Break (4.9/5 stars, 1,277 reviews) which offers volume discounts, free gifts, BOGO & upsells; and FBP | Fast Bundle Product (5.0/5 stars, 1,481 reviews) for creating bundles and volume discounts. Both are free to install and built for Shopify, offering similar functionality for managing promotions and boosting average order value.
To set up a tiered discount in ADU, navigate to the app dashboard and select 'Create Promotion'. Choose 'Tiered Discount' from the promotion types, set your discount rules (e.g., 10% off for $50+ spend, 15% off for $100+ spend), configure which products/categories apply, and customize the display style. Test the promotion before publishing to ensure it works correctly across different cart scenarios.
In ADU, select 'Create Promotion' and choose 'Gift with Purchase'. Set your trigger conditions (e.g., spend threshold or specific product purchased), select the gift product(s) and variants, configure quantity limits, and customize the display messaging. You can set up multiple gift variants and configure whether gifts are automatically added or require customer selection.
If ADU discounts aren't showing in cart, first verify your theme integration is properly installed by checking the app's theme extension settings. Ensure promotions are active and meet all trigger conditions. Check if there are conflicting apps or custom scripts interfering with discount display. You may need to regenerate the theme integration code or contact support for assistance with complex theme compatibility issues.
