Rapi Bundles Builder & Upsells

I was excited about this app however as I went to set up the bundles I realized that it is a little limited for what I was hoping to use it for. I am looking for an app that will allow me to create bundles that I can add collections to the bundle that allows the customer to choose from different collections to make their bundle. Such as adding one style of earrings to the cart and then adding another 2 different styles to complete the buy 2 get one free bundle. This app does not offer that type of bundle and I am not even sure that it is possilbe. However when I reached out for help their customer service rep, Authur was very helpful, so thats bonus. I am not sure I will keep this app long term, but I will try one bundle set and see how it goes.
