Rapi Bundles Builder & Upsell

I would definitely recommend an app like this. It does what it says, and more. Moreover when you're starting to use it, a customer support agent proactively approaching to know how you're fairing with it, is encouraging and exhilarating.

I particularly enjoyed the help I got from one of their agents, Arthur Fynn, who was as professional as you can expect, plus having to go informal sometimes to keep the engagement lively and fun. That's what customer service should be par excellence.
