Were do I buy

You can find it at Wal Mart. If not try contacting them for specific distributors in your area:

 saw that show with it also and was intruiged. it's basically carbonated fruit. unfortunately there is no "store locator" on their website, so you'll just have to wing it. on the show, they did say that you could find it at your local grocery store in the produce department (the fridge section where they keep the pre-cut fruit). unfortunately i have yet to find it in my area. you'll probably have much better luck in NYC.

you can "contact" them through there website and ask. they may respond.
