For all of you confused about how to get your CE items, and no email with no special code, here's how you do it.
After some super sleuthing, I finally figured out how to get your CE registration code without them sending you an email if you ordered from SE store:
go to store.na.square-enix.com/orders
enter your order # from your digital river receipt email, should come from an address like
webhelp.v4@digitalriver.com check your spam folder, and your SE account password, the page it sends you takes you to an order status page, your registration codes will be there plain as day. Take that code and go to the FFXIV Mogstation -
https://secure.square-enix.com/account/app and go to account services then click on add pc service, enter your code and voila! 30 days game time and in game shinies.
