tldr; Basically what I’m looking for is the digital way of selling a dvd, which was the previous way we had to make some extra money for the club.

We’ve created a few videos from a gymnastics show for kids and we’re looking to try to use those to get some extra money into the club. We’d prefer not to put the videos on youtube for everyone to see, because obviously not everyone wants that, but is there a simple and preferably automated way to monetize sending/showing the files to people who donate?
