Great app, powerful, easy to use, and well documented. The very few times we had glitches the support team was very helpful.

Stackable is a great app and their support is awesome too! (Sammy rocks!) They have updated their features quickly and are willing to discover new solutions for users. We highly recommend this app.

This app has changed the way we do business. Each sale campaign accrued a lot of abandoned carts because we were unable to offer free shipping with our sales. Not any more!! We are really pleased with our early bird sales so far and we hope to see fewer customer comments about this now that we've added Stackable. I would also like to mention the awesome customer service. Many apps are slow to reply, but these guys are speedy & provide excellent & informative replies. I give them a 9/10 for this app. Waiting on multiple free shipping codes to give a 10 rating.

This app has solved all of the problems we've had with the Shopify discount system. BOGO in addition to adding another coupon? No problem. Adding multiple coupons? No problem. Having multiple coupons but only allowing certain ones to work together at the same time? Again, no problem! This app is amazing and Sammy and his team have been available at all hours, day and night, to answer any questions and assist with integration to our website. Thank you guys. We highly recommend everyone get this app!

Great app and great support. Definitely 5 stars. Been looking for something like this to help sales. The automated discounts in Shopify are so limited that you really cannot use them. This solves all the issues and integrates really well. Must use app for all stores.

I was looking for an app to enable discount codes to be used alongside store wide discounts and Stackable really seemed to fit the bill. Once I'd worked out the setup and had a few messages with the developers it was clear these guys are super customer focused and have a great product. Once initial setup was in place I signed up to the pro account and had some customisation to show the discount far more clearly in the cart directly which I know has impacted conversion, of course when the customer can see what they are spending/ saving before they hit the checkout it really helps them have confidence and follow through their transaction. Black Friday with the app in place we saw an increase in conversion of 1.5% over that promotional period, that's an increase of over 30%, and undoubtedly sales that otherwise wouldn't have converted. Would highly recommend, especially as I know there are now more features in the basic package too.
