Isn't it still buyable through the kiosk in the apartment? Or did they remove it from there too?
Come check out my Twitch TV channel, will be streaming various PS4 games from time to time http://www.twitch.tv/reddaxel
When the founder of Red Bull died earlier this year, Red Bull elected not to continue as a 3rd party developer in Home and removed their Red Bull public spaces, mini games and other content. The personal space was last to go and remained a lot longer than anybody expected and was the only way the last of its content could be purchased.
I guess its all finally gone now
