doublevr We can have an upgrade 50 downloads for $19.99
If the goal is to let frequent downloaders pay for the additional traffic, I don't think this offer is attractive. For $20 you can get a second subscription with the competition and an additional 600 downloads per month plus their exclusive content. So I think this approach will only reduce downloads but will not generate any significant additional revenue.
When I am downloading videos it is because I want to watch them in the highest bitrate available and I can't do this by streaming. I am not building any archives. My days are numbered and I am hardly able to keep up with all the new videos coming out every day.
