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.

[EX Q]: I love VitaMuffins, but my supermarket sells one box of 4 muffins for $6.29.  Instead I bought the mix, 3 boxes for $16.00, and each box makes 12 muffins. Instead of $1.62 per muffin, the mix only requires water & eggs and works out to about 48 cents per muffin, and very easy to make. That's a great deal.
[EX A]: Positive

[EX Q]: I am the biggest fan of mushrooms you'll ever meet, but these are really disgusting. They taste like dirt. I have to imagine better quality truffles (if these are even truffles at all) are muuuuch better. They'd have to be. There'd be no comparison. These are really bad.
[EX A]: Negative

[EX Q]: I'm really glad Amazon carries these, they are so much better for you than regular chips and actually taste good too.  We haven't found a flavor we didn't like yet.  I'll probably use the Amazon subscribe feature to get another $3 off as we will go through these fairly regularly.  Awesome chips!
[EX A]:
Positive
