Part of the deal for this 'bundle' is a code you can pass on to a friend to save 20%.
Would anybody who has already purchased care to be my code sharing friend?

Most of the apps are shovelware, but a few are potentially useful.
Not what youre looking for, but a good amount of those apps are available on Setapp (https://setapp.com/). It's about $10ish a month but you get subscription access to heaps of stuff. I find they add a new app every week. Really worth it if it has what you need.
