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.
Stackable is the only Shopify app I found that allows you to link discount codes—an incredibly helpful feature we couldn't find anywhere else. I had an issue during install, but Sammy from support responded right away and solved it quickly. Excellent app and even better support!
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.
It has taken some practice getting used to how this app works, but don't let that fool you, as Stackable is by far the most intuitive and powerful discount app I've used. It even serves well for automatic bundling, should you need that. However, by far the most impressive part of Stackable has been the support team - some of the fastest, most knowledgeable and friendly service I've experienced. I'm excited to continue learning the ins and outs of this app, and experimenting with its many features.
Some of the quickest and best support I have received from any app. Can easily use multiple competing automatic discounts along with manual discounts (If the customer has one), competing to ensure that the customer gets the best price. Additionally works flawlessly with gift cards.. customers can input their gift card code without any issues. Highly recommend this app!
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!
They changed the App all my discounts and heder with it gone leaving the webiste ducked
Great app, powerful, easy to use, and well documented. The very few times we had glitches the support team was very helpful.
