@Bazza, I completely agree that it is most common for people to attribute the perceived value a product based on what they paid for it.
I can speak from my own experience and say that I am unlikely to use many on the apps I got in a bundle because most of them were just justifications for me buying the bundle to get a single app.
However, I do see the value in participating in programs/platforms that allow for a large number of purchases. The iOS App Store is a great example of how this kind of distribution can be effective.
Mojang developed the MineCraft Pocket addition and released it for $6.99 after spending a substantial amount to develop it. Why would they value their software at such a low cost? Because the App Store is a platform that put it in the hands of hundreds of thousands of users in the blink of an eye.
It is highly unlikely that the 5.8 million downloads that occurred in 2012 are all still active users, but the $40.54 Million dollars that was generated in that year allows for the growth of Mojang, Apple, and the various companies that are involved in the supply chain.
Lets say that a bundle of 10 apps that is $17.99 and has 2,000 purchases. That would be just under $36,000 in gross revenue. Perhaps the distributor takes 30% like Apple so there is just over $25,000 for the developers. If split equally amongst the developers then a 1 - 2 week promotion generates ~$2,500 in Net profit that likely wouldn’t have occurred otherwise.
Again, I do not disagree that the price people pay for something has a huge impact on the perceived value. Just that this is good business and is actually helping out us users who continue to thrive through the growth and success of Realmac as a company.
Also, I acknowledge that you likely know all this already and apologize if my response is a bit long winded. I figured I would be detailed for those users who have a similar view of bundles but may not have listened to the podcast and/or are unfamiliar with how bundles work.
