The reviews are overwhelmingly positive, with most users praising the app for solving Shopify’s limitation of only allowing one discount code at a time. Merchants repeatedly mention that it enables stacked promotions, automatic discounts, free shipping offers, tiered pricing, BOGO-style setups, and combinations of promo codes that were otherwise difficult or impossible to run. Many reviewers say it is easy to use, well documented, visually polished, and effective for sales events like Black Friday/Cyber Monday. A major strength highlighted throughout is the support team: users consistently describe the support as fast, knowledgeable, friendly, and highly responsive, often going above and beyond to help with setup, custom themes, integrations, and troubleshooting. The negative feedback is limited but important. A few users mention setup complexity or needing time to learn how the app works, and one reviewer wanted more flexibility for BOGO gift variants. There is also one strongly negative review complaining that an app change caused discounts and header elements to disappear, suggesting a possible compatibility or update issue. Overall, the reviews indicate that the app is highly valued for its discount-stacking functionality and exceptional support, while the main drawbacks are occasional integration hiccups, learning curve, and a small number of stability or theme-related concerns.
