Mix and Match Bundle Builder

This app is the only one I have found that lets me cross sell bundles in a smart way. I can select the items I want to appear with each item, as well as where it appears on my item page. I had a little difficulty installing, and reached out to their team. They made it painless to get it installed and working smoothly. This is the upsell / cross-sell / bundle package I was hoping to find. It works, and they were extremely helpful and fast.
