Even with small containers, they don't fill them up.  These little tins are less than half filled and at the price charged it seems a rip-off. Is there some exotic ingredient as costly as gold contained in those tiny squares?  Or how about the cereal ploy, they were filled at the factory but settled in transport. Can manufacturers be honest in their dealings?

I had high hopes for the convenience of this product.  My daughter LOVES hot chocolate. This really was a total disappointment.  I threw these kcups out.  If you use the smallest setting on your Keurig, you get 3 oz of watery hot chocolate.  Larger settings are not drinkable.  Save your money and get cocoa packets or a good tin of hot cocoa - and take advantage of the instant hot water the keurig provides.

I recently found out that I am allergic to wheat and milk.  As you can imagine, this severely limits my snacking options.  My local grocery was clearancing all of their organic section, so I tried these.  They are SO GOOD!  I love salted & plain rice cakes (did before my diet change too) & these add an extra punch of flavor and crunch!  Yum!
