Kaching Bundles App & Upsells

Absolutely incredible is the number of features that come built-in. The split testing function works great and has allowed me to split test price, bundles, and copy. I was able to get ride of Intelligems and UFE Upsell completely. Customer support is ridiculously fast - I'm used to having to wait 20+ hours for responses from UFE but these guys start DMing almost immediately. They have helped me with custom coding on several of my bundles. i've also really enjoyed their cart, and upsell pop-up. Haven't tried the post purchase because of price, but all their other apps are affordable compared to Zipify and UFE Upsell.
