Bundle Bear ‑ Volume Discounts

This app has potential, but it uses its own propriety technology vs. integrating with the Theme. We encountered enormous difficulty trying to get it to work, having nuanced conflicts other installed apps and never finding a good solution. The support team spent time trying to sort it out, so providing 2 stars here exclusively for their persistence. But we needed to use another bundle app that works more fluidly with the theme out of the box.

The app is not robust. The reason 1) the app does not replace the previously stock bundles that I had on my website. Tech support stated they are unable to do this.
2) The app does not allow me to add multiple different offers on the product page for example offer a) buy x get y free offer b) buy a + b get c % off again tech support said they were unable to do this.
