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 purchased these in lieu of the V8 Fusions since they sell for $2.08 per can on Amazon Marketplace (approx double the price Safeway sells them for).  First of all, they only contain 10% juice and the first ingredient after water is High Fructose Corn Syrup.  They essentially sold me Soda with a V8 label on it!  If I wanted to buy pop, I'd get a 24 pack for $8 not $30! Honestly, if you want juice, go to your local grocery store.  These are terrible for you, over priced and they taste horrible.  I would've sent them back but I figured I'd give it a try.  Now im out $30.  This left a bad taste in my mouth in more ways than one.  Oh!  I should also mention that these did not arrive in a 'weather-resistant tote' but rather were delivered to me in the original packaging.  The plastic was loose and a can fell out when I carried it in.  Not using Amazon marketplace again!
Example Output: Negative

Example Input: We have three cats, the youngest is about eleven years old, another is fifteen and our oldest is, well ancient.  That is what the vet told us ten years ago.  The youngest is a blob.  When he lays down, he looks like a footstool. The other two are arthritic and skinny.  Since we had such success with Canidae Platinum for senior dogs, I figured that we'd give it a try for our cats.  I'd had them on low ash Purina One Urinary tract formula for their entire lives and thankfully we had no UT problems.  Buster, the youngest, is still a blob after six months plus on Felidae for Senior and Overweight cats.  However, the other two are now much more active and we can tell that they are really "feeling better" since we changed their food to Felidae.  Even Prissy, the ancient one has started to play and tease the dogs by getting them to chase her, where before when she was on Purina One, all she wanted to do was to sleep.  I think that if you can get your cat on this fairly early in their weight problems, it'll be more effective.  However, the glucosamine will certainly help your older fur balls have a happier life.
Example Output: Positive

Example Input: These are absolutely scrumptuous!  My husband and I both love them, however, as another customer put it, they are expensive to ship!  The cost of shipping is more than the tartlets themselves are!
Example Output:
Positive
