DC Universe Infinite should have a 3 tier subscription service. $75 per year for basic, $120 per year for basic and 3 series delivered on the same day as print comics, and $240 per year with basic service and access to all titles delivered same day as print comics. I personally would do the $240 option if it was available, as I currently spend over $30 a month on books anyways.
I might do the 120 option. No way am I doing 240. I would probably stick with what I have.
