I have purchased this product in the past through Amazon for my twins and it was good. However, the last time I ordered the 6-pack in June, the cereal was stale and smelly. I opened a few cans and they were all the same. I called Amazon customer service and they were very helpful and gave me a refund. I don't think I will purchase this item again through Amazon, although I do purchase the majority of items for my twins(including diapers) at a great price from them.

Ex Output:
Negative

I am very pleased with this selection.  I have not tried the other hot cocoa brands for Keurig but this one is awesome!  I bought the milk chocolate.

Ex Output:
Positive

I purchased these little treats as stocking stuffers for our little furry friends.  Both Yorkies LOVED these treats.  We had to finally buy more since they liked them so much.

Positive
