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 started using <a href="http://www.amazon.com/gp/product/B008EMA3AS">Lourdes Gourmet Chimichurri Sauce</a> on my grilled steaks and fell in love with it.  Now I'm putting it on my chicken, vegetables & pasta.  I'm turning into a real chimichurri addict.
Example Output: Positive

Example Input: I bought these for my vegan father who LOVES the curry kale chips by Rhythm Superfoods (my 22 month old daughter, husband and I also like them)!  Thought I would give him a new kale chip flavor--BBQ--as part of his Christmas gift. Although a different brand than we typically eat, they sounded good. First, I was disappointed to see these chips are not kale in its natural curly form but pressed into round, dog-snack-looking discs. Luckily I tried them before giving them. I spit it right out! Was it just me? My husband also tried one and couldn't finish even one chip.  I have a pack of 4 that cannot be returned... what a waste of food and money!
Example Output: Negative

Example Input: Cost was $48 at time of review.  Only $25 at other sites .... buy elsewhere!  Sometimes prime is worth paying an extra dollar or two. I will be comparison shopping a little more now.
Example Output:
Negative
