PROBLEM: Go to Costco, and you can buy lower than this  price per oz. Currently $32 ($3 off regular $34.99)+ tax for big size = 0.83$/oz.  Besides, it is more convinient to return if you kid does not like this formula  Be careful, many times some sellers over price a product, and still make the product rank in the best sellers.

PROBLEM: This food is great - all ages dogs.  I have a 3 year old and a puppy.  They are both so soft and hardly ever get sick.  The food is good especially when you have Amazon Prime shipping  :)

PROBLEM: This cocoa powder has a deep, fruity taste- I highly recommend it.  I recently bought a vitamix blender, which means that I now make 5 smoothies a day.  This cocoa powder, plus some almond milk, frozen fruit, yogurt, and a dash of maple syrup, makes an excellent "milk shake".  Disclaimer: I like 99.9% of all chocolate, so take this positive review with a grain of salt.
