They probably discontinued it because it was rootie-tootie fruitie like most of the teas sold at Teavana. That, or it didn't appeal with people's inner cakra.
Like Republic of Tea (or as I like to call, the Autocracy of Ripoff), Teavana is there to sell an image, not tea. You aren't paying for their product, but for the privilege to purchase their product, patron their trendy, minimalistic decorated stores, and fashionable packaging (take a look at the pretty little package that RoT's products come in, or stop into a Teavana shop if you don't believe me). I'm surprise that both of them aren't selling Ayurvedic remedies or specialty blends that match people's astrological sign.
Now, that's not to say that you won't find good teas from both of these companies. My sister, completely ignorant of what to give me for my birthday last year, purchased some gyokuro from Teavana for a reasonable price. It was lovely, with a smooth vegetal essence, with that slight buttery note that gyokuros should have. It was a real class act.
But I'm not amused when looking at their products with a gestalt outlook. Even their flavored blacks and greens I can replicate on my own with minimal strain on my wallet.
In general, I can find blends of a better quality, and for a more reasonable price just looking around at Adagio, Upton, Mark T. Wendell, etc.
