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 bought this coffee because its much cheaper than the ganocafe and has the organic reishi mushroom as well as other healthy antioxidants.  I didn't expect it to taste good, but it actually does!  I've only had it for a few days and for $5 its totally worth it.  My sisters all take ganocafe but now I'm introducing them to this less expensive similar coffee.  I will follow up on this product in a few weeks.  :)
Example Output: Positive

Example Input: Bought this product as a gift for my relative in Asia but was ashamed that was told by my receiver that it has been expired 3 months ago. It a waste of my money whereby I can't make refund due to product is not with me.
Example Output: Negative

Example Input: I love this!  Such a great product for all us gluten free folks!  It works the same as the regular Bisquick. Their website has tons of gf recipes too!  This makes delicious pancakes and 'magic crust' pies. Yummy!
Example Output:
Positive
