We wanted the Baconnaise lite after seeing the product on Oprah. We looked forward eagerly to the  prospect of that great bacon taste. The decision in our house was 1 for and 1 not so. The taste is there, the "greasy" taste was also. I won't buy the product again.

Sesmark makes a very high quality rice cracker and then proceeds to ruin it by loading it up with so much salt as to make it inedible.  USE CAUTION before buying this item since there are NO RETURNS and you might find yourself with a throw away.

I have had Green Mountain coffee before, but had not tried the French Roast.  I am just realizing that there is a taste difference between different manufacturers, even with the same types of roasts.  The Green Mountain French Roast has the flavor I like and was expecting.  The price was reasonable and my order shipped quickly.  My only disappointment was in the shipping packaging.  I knew that I was ordering 2 boxes of K-cups but was surprised to see how big the shipping box was.  There was room for 3 boxes, with the extra space filled with bubble-wrap, which seems wasteful to me.  But on the whole, I am very happy with my coffee!
