Umm, You can buy the Collectors Edition band in-game for 1 million credits
There is no CE band. That's for the VIP lounge.
It gets you up the elevator and you can put money in the jukebox and talk to the VIP vendor while you're there.
Just because you're in the VIP lounge doesn't mean that the CE vendor will talk to you, much the same way the Sec Key vendor won't talk to you if you aren't using the security key.
