I buy for a long time at Amazon and was what be offered here in the products, also never really disappointed until this time ... me, the question arises how a price of 20 to start with this tea, I have a lot read about this tea its supposedly stimulating effect, the feel good after drinking etc, I do not expect much, but that one is bad and uncomfortable after eating a realization too much of the good and it should to pay 20 Euros? I do not see, the packaging would not open I would let the powder go back by return mail.
