Anyone tried it? Is it worth the $16.25 a box or is their a comparable grocery store product? Ice cream is my weakness so this would be a good treat for me.

I like it. I have tried them all and the coffee is my favorite.
Instead of the few ounces of water and crushed ice, I just tried 6 oz. of water and 4 ice cubes and blended with a magic bullet or hand blender and it was like a thick shake!
