I just did a search on Total Wine's website and didn't see any anywhere, even California. I plan on going there this weekend to pick up some Modern Times, so I'll keep an eye out.
Not at TW or Bevmo yet, but smaller shops do. GCM liquor in Gilbert does for sure. I picked up a couple different selections including bomb! from them. They say it will be year round.
Ill confirm that - BOMB! is now a year-round release. That said, there may be small gaps in availability if a market sells out and has to wait for more to ship. But its definitely going to be available annually and in short order should be pretty easy to get.
