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: 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 product had pretty good reviews so I thought it would be safe to buy 4 packages, so I did. Boy am I full of regret now. I'm stuck with 4 packs of these beans and I can't return any them. The moment I opened the bag, I should've known. It had a stale sour smell to them. But the optimistic side of me said, these beans look fresh and plump, maybe it won't smell like that once I scrape the seeds out. I was wrong. I made two test batches to see if it was the salt I was using to make my vanilla salt but they both have that weird sour, rancid smell. I've made vanilla salt before so I know what it's supposed to smell and taste like. Unfortunately, even after a few days, this smell isn't going away. I was really looking forward to making jars of vanilla salt to give out as cheap gifts. But now I need to go buy more vanilla beans to replace these which is going to end up costing me. I'm so disappointed. I haven't cooked with these seeds so I don't know if the taste and smell transforms with heat or with any other mixed in ingredient. I know for sure though that if you're looking to make vanilla extract, vanilla sugar or vanilla salt, I HIGHLY discourage you from buying this product.
Example Output: Negative

Example Input: Plum products are such a wonderful and yummy idea for the toddler, heck even the adult from time to time. I keep a full stock of every flavor fruit pouch Plum makes for toddlers. They make a great snack to throw in the diaper bag or back pack, whether you are packing a for a trip to the store, school lunches or going to Disneyland! These pouches have saved the day many many times. I have even grabbed one or two to add to my lunch when no other fruit was available for me, and it was really good! I have and will always recommend Plum to every parent I know!
