I bought this product online because, although it is a Kellogg cereal, I cannot find a retail store which carries it, and incidentally I would like to know why. I called Kellogg and they could really give me no good answer, and suggested I try another product of theirs, which i found not as good as this. I appreciate that Amazon offers this, and I will continue to order it. By the way, it really keeps me "regular", better than any other cereal. Try it, you'll like it.

Ex Output:
Positive

I got this through a Decaf Keurig assortment pack (also from amazon) and while I have enjoyed all of the flavors - thisone was so weak - I had to post a review.

Ex Output:
Negative

This is my 2nd review for this product. The first one was supposed to be 75 words. That would be too long for this item. The product itself is good but the price for shipping for such a small item was ridiculous. The package was small and light weight but I was charged $6.78 for shipping of a $4.99 item. I have bought many items from amazon.com and it seems here lately that the shipping has gotten totally out of hand. I bought several items and the shipping was all together. Therefore I did not know how much was charged for each item. I will not buy from this vendor again since they are making money on the shipping. Enough said.

Ex Output:
Negative
