Where can I buy Mountain Dew Livewire?

I have been in love with Mountain Dew Live wire since it was released for the summer of 2005. It's singlehandedly my favorite soft drink of all time! However, PepsiCo stopped supplying it after that summer. Recently I was on the Mountain Dew website and it has Livewire listed as a current product with the new Mtn Dew logo. I was wondering where the heck could I possibly buy it, whether physically or if I could purchase it online? I live in Los Angeles county.
