The Apple Store (since 2008) and the Google Play Store (a few months later) exact a thirty percent tax on all transactions. That’s 30%! This is called the Apple Tax.
Folks who sell through the Apple and Google Play stores believe that is an obscenely high fee. Color your Big Red Car amongst those who hold that opinion. [Note: In this blog post, I will consider the interests and behavior of Apple/Google as one and the same for simplicity.]
