The only reason for the 3 stars was the packets the individual teas were in.  I love this tea, I have the ones in the tin on auto delivery.  I was taking a trip, and ordered these so I could take some with me on my trip.  Prior to leaving home I took some out of the box and put them in my suitcase.  I got to the hotel and tried to open the little packages.  Impossible to open the individual packages.  No knife with me, I ended up using a toe nail clipper to open the individual packages of each tea.  Hopefully this was just a problem with the first box, but I would not recommend buying this tea in the boxes, go for the cannisters.  If you do buy the boxes have something near by to open each and every packet of tea.

I'm dieting, and I use these as a "treat" to myself, when I'm craving chocolate.  I usually brew one of these & one of my coffee K-cups (either plain or hazelnut).  For 60 calories, it's not a bad way to satisfy a chocolate craving when you're on a "calorie-budget!"

My parents fell in love with 'San Francisco Bay Coffee Company' coffee, which use to be available at our local AZ Costco. For christmas I looked every where for this coffee & found what I thought was a great value on Amazon. When I bought it (12/21/11) there was "No Image Available", should have been my first warning sign. They had lots of pictures of the 12oz bags of coffee from the San Francisco Bay Coffee Co, but I wanted something bigger, and this was 2 lbs. Now there is a picture availble, but if you look closely it's "Roger's Family Company" coffee, who is technically located near the San Francisco Bay Area. So if you're in love with San Francisco Bay Coffee Company, don't buy this coffee. But on the upside, since I waited till the last minute to buy it, I gave it to my parents for christmas anyway & explained what happened, but they said the coffee was pretty decent. So still makes a nice cup of coffee, just not San Francisco Bay Coffee Company coffee.
