When I was in Brooklyn last month, Jenny, Anna, Misha and I stopped by Starbucks and I bought their Iced Passion Tea. I think it was only around $7 for 6 pouches, each making a pitcher(unfortunately I cannot find any information on their website).
I absolutely love it! I actually add more water than recommended in the directions to make it a bit weaker, but it is still very refreshing, fruity and flavorful.
If you can find this blend in your local Starbucks, definitely give it a try!
