Stackable: Combined Discounts

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.
