More details about Stackable
Product description
Stackable is a tool that combines multiple customer promotions, from automatic discounts to manual codes, providing convenient savings references for shoppers. It organizes these discounts into a "Stack", calculating savings automatically and notifying customers in real-time when savings occur.
AI summary
The Stackable app is a Shopify discount management tool designed to overcome Shopify’s native limitation of applying only one discount per order. Its core functionality enables merchants to combine multiple automatic and manual discounts, including tiered pricing, free shipping, and loyalty-based promotions, while ensuring clarity for customers through real-time cart updates. The app integrates smoothly with themes and other apps, supports multi-currency setups, and offers customization options for styling, though advanced design modifications may require CSS or JavaScript expertise. A standout strength is its responsive and knowledgeable support team, frequently noted for rapid issue resolution and assistance with theme integrations or technical adjustments. However, some users report limitations in granular control over discount eligibility rules and styling flexibility for certain elements. The app is particularly effective for high-traffic events like Black Friday, with users highlighting its reliability and positive impact on conversion rates and average order value. While setup is generally intuitive, complex use cases may require initial support. Overall, Stackable fills a critical gap in Shopify’s discount functionality with robust features and exceptional service.

The customer service here is incredible. I had some problems in getting set up because Shopify had changed something on the back end and they fixed the app very quickly and got me going. I wish every app had such attentive support!
★★★★★Quilling Card Wholesalefrom United States · 26 August 2025
Just needed a way to stack percent discounts and free shipping discounts and this did the trick. You can even segment by collection which helps with excluding other products. Happy with functionality. Thank you.

This is the best automatic discount app in the shopify app store hands down. We've tried them all! AND the support team at stackable will restore your faith in humanity. They truly are top notch.
- DBDurhams Bee Farm★★★★★
I had to take a moment and write a wonderful review on the Stackable Discount app. We have had a very hard time finding a solution that worked until we found this app. We recently switched to Shopify 2.0 using the Dawn theme. In the process we had to find a new solution for discounts because we have one app that provides discounts based on loyalty actions and we also provided quantity discounts on our products. It seemed impossible to do both in Shopify as it does not natively support that functionality. But thank goodness we found Stackable Apps and it works perfectly. We now provide the quantity discounts as well as "loyalty discounts" (in the form of coupon codes). This is also much smoother than it was in the previous version of Shopify. The support team was very helpful in getting a few things tweaked and helping us to get it working just like we needed. I highly recommend this app and the support team! I am sure you will be as pleased as we are.
About ShopDigest
The Shopify ecosystem, shown through the work
ShopDigest is an independent directory of Shopify work. Developers, agencies and experts publish the projects they’ve actually shipped — migrations, rebuilds, custom apps, headless storefronts — with the results attached.
For merchants, that means judging a partner on evidence instead of a sales page: browse real builds in your category and budget, then reach out directly. For builders, it means one profile that keeps working after the project ships.
No commissions, no pay-to-rank placements. The best work rises because people save and follow it.
