You can have the 12X boost permanently removed. Submit an in-game request and tell them you don't want the boost. This is what the call center told me to do, so I did and 2 days later I got an email from customer service saying they had removed it.

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.

There's no option to add anything except a physical one on the account page yet, so why not wait until they implement it before asking why you can't figure out how to work it? You'll get the codes you need when adding the app to your account.

Doesn't matter what you consider it. The launch is the 20th.
