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.

Example Input: I feed my 10 year old toy breed this food and she hasn't complained yet.  Was feeding her Eukanuba her whole life before the dog food scare.  Switched then to only organic brands like Wellness.  This product has been the best deal on organic dog food I have found and with the subscribe and save...perfect!!
Example Output: Positive

Example Input: these are grossly overpriced.  It is a package of three boxes but when you take into account that they are a dollar of two per box than they should be, you then have to pay for shipping.  Sorry, I would skip them.  My local grocery store carries them and a box is anywhere from 2.98 to 3.49 each.  Although these are healthier than some other cookies, you still have to watch the fat, sugar and salt contents.  Whole foods are much better for you but in a moment or two of indulging, these fit the bill.  Just the price on this site is ridiculous!  Ask your grocer to start carrying them.
Example Output: Positive

Example Input: This is my favorite coconut water! Having traveled in Asia and being able to get someone to climb a tree to harvest a coconut and then open it with a machete, nothing I found in the store came close... until I found Taste Nirvana. The other brands are mostly from Brazilian coconuts, whereas this brand uses Thailand coconuts and it makes a difference.  Truly happiness in a bottle. It's a little pricey, but I can't get enough!
Example Output:
Positive
