There was no "Digital Deluxe Collector's Edition". There was Digital Deluxe AND Collector's Edition, but they were two different things. If you paid that much for a Digital Deluxe version, I'd be getting my money back. DDE was only $80 and doesn't include a security key.
The CE version include a security key, which you can activate when it arrives on the 20th and access the store in-game.
