After reading all the great reviews, I optimistically ordered some of this tea. I've had problems with sinus congestion very often this winter and have tried all kinds of remedies with little success.  Unfortunately, this really didn't do anything for me.  The taste is OK (bearable), but it did nothing to relieve my sinus congestion.  (So far the only things I've found that have helped me somewhat are the Vicks personal warm mist humidifier and Neti Xlear)

My daughter loves these snacks and can't get them in China where she is working now so I ordered them for her. Very satisfied and she was very appreciative.

Love this coffee, so I was rather disappointed when I recieved this particular shipment.  The box said it was a pack of 50, but there were only 47 K-cups in the box.  And one of the K-cups had come open, reducing the quantity to 46 and creating a mess of coffee grounds in the box.  Not sure who takes the blame for this - the coffee box was sealed and included inside another box with other items, so that leads me to believe fault lies with "The Coffee People."  I suppose if many others are experiencing this same issue, it may be time to choose another coffee provider.  March 29 Update: Discovered 8 other faulty cups in this batch - Top seal would come loose while brewing & cause grounds to overflow from top of K-cup, or the internal filter would leak by and puke coffee grounds into my cup.  I was beginning to suspect a faulty brewer,but when these same results occurred on a second and third brewer, the problem lies in the K-cup...
