Anyone get the Tron *Digital* bundle? I need to know more.

I have to assume that the bundle the "Buy the bundle" button is referring to is a 3-movie bundle. However, I have no way of knowing that for sure. When I click on the "buy the bundle" button, it asks me to enter my purchase restriction code, which usually means they are going to charge me right after I enter it, iirc. I can find zero info Amazon on this bundle or anywhere else. I understand that I don't really own it for ever, but I just want the 4k version of all three movies in a convenient format. TIA for any info!
