I believe that the Casino Verite Blueprint, which is $47 can only be shipped to you in CD form, not downloaded. The same holds true for the full blown version, Casino Verite' Blackjack, which is $90.
The $47 version is upgradeable to the $90 version, but I would recommend purchasing the $90 version out right. I'm fairly confident you would wish to upgrade, and buying the $90 version up front would save you time delay and extra shipping.
I would also recommend that you purchase it here.
