I talked to someone who lives in the UK and they bought the CD. It had a bonus track that the US didnt get. Actually it was just TimeBomb, and Nikki had that on the site around Christmas for a few days for a Christmas present to the fans.
Maybe your store is the only one not getting it. Can you try another?
It is a very good CD. Hopefully you will be able to find it.
Even other bands fans are digging it. I found this at the LA GUNS message board

You gotta scroll down a bit, but nothing but Rave reviews.
