Braaaaaapp review for Zoorix: Bundles & Cross Sell

I've tried many different apps to upsell and recommend products, many of them paid, and I must say that this one not only works perfectly, it amazes me how it is free. To top that, only their customer service, which is probably the best I've dealt with in years. Not only did they help me adjust some things I needed, but they also gracefully heard some ideas and notes I gave them on possible updates to their already great app. Definitely a winner!
