There is no digital deluxe collectors edition. You have the digital deluxe edition, which does not have the physical security key (being that it is a digital version) and does not have access to the CE vendor. You will be able to enter the area the vendor is in, but not buy from them. Or you have the collectors edition, which has these things. Since you bought from a Gamestop, you obviously have the physical collectors edition, right? Really, you should know what you're buying...
