You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Ex Input:
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


Ex Input:
The initial taste does hint of something, but then the apple and grape juice filler comes to fore and dominates the after- taste.  Comparing this to the Black Cherry drink, Kiwi Berry has a better taste and after taste.  However, if you would have told me that this was the Black Cherry flavor, I would have thought that to be true.  I could not note any significant difference between flavors.  The carbonation offers no benefit in the taste or feel category.  The price is high - about $1 per 8 oz can.  If I want juice, I'll stick with real juice without the carbonation.

Ex Output:
Negative

This was a great bargain, worked out cheaper than if I had purchased them at a wholesale discount store plus it was elegible for free shipment...BONUS
