I have managed to find these crackers in other countries on our travels but had run out. I love that they are individually wrapped small packets in a stay fresh container. This makes them great to carry in my purse, take to work or on airplanes for snacks etc. Also love that they are not overly salted like so many American brand crackers. Company that shipped them did a great job - fast too!

This is my favorite K-cup coffee (I've tried about twenty different types) and, so far, everyone I've served it to really likes it a lot. Even the pickiest coffee connoisseur I know thought this k-cup made an excellent cup of coffee. Two non-coffee drinking friends wish they liked coffee because they love the sound of Caribou Mahogany.
