BundleSuite Bundle Builder

Positives:
Very easy app to use.
Super fast and very good customer service. :)
I can’t find a limit to the amount of variables.
There are two templates so far, and a third one seems to be on the way. I think the one I chose was very aesthetically pleasing and professional. I can customize much more than I expected, such as colours, text size and text thickness.
I asked for a specific customization that required code and they actually solved this for me quickly and exactly like I wanted it.

Negatives:
You have to stick to one language so far. We are a store with two language options, and this is a downside to us.

If you only want one language or don't mind one language in this part of your store, I would highly recommend this bundle app.
