Reign of the Supermen digital release

So it doesn’t come out on DC Universe till the 29th, but it says it released digitally on the 15th? So where did it release digitally? Anyone know?

It’s available for purchase on sites like Amazon, Vudu and iTunes. DC Universe gets it the day of the physical release.

Is it available at Amazon now? I checked early Tuesday morning and nothing. I don’t use iTunes but I did see it on Vudu and Fandango. I’m just going to wait until it debuts here.
