Ex Input:
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!"

Ex Input:
My dog thinks he was born into the gentry and is entitled to fine dining each evening.  Accordingly, he will not eat plain kibble.  A scoop of this on his dry food, a little water to make gravy and we're good to go.  Ordering a case from Amazon was way easier than picking up individual cans at the pet store, too.  All in all, a success for us.

Raw, Organic, Fair Trade, Tastes Great... What's not to love? My hope is that as more people buy their amazing chocolates that the price will come down a bit.
