i'm actually drinking it right now! i bought the $4.99 concentrate because i figured it would be cheaper per serving than buying it in store. It tastes JUST like the real thing. The ingredients of the concentrate are: water, black tea, black pepper, cardamom, cinnamon, ginger, cloves, star anise, cane sugar, honey, ginger juice, natural flavors, vanilla and citric acid. So if you try to add all these things it'll taste like the real thing. However, the 'natural flavors' seems like a coverup for some secret ingredient. so maybe it will be a good replica, but not a copy. let us know what you make. this $5 carton is cheaper, but still a ripoff!
there is a company in brooklyn which is selling it for 3 bucks, the only catch is that either you hv to pick it ur self on weekdays or you have to pay shipping charges, however the shipping in nyc is free if you order more then 50$, that's wat i do :S
