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: This oil is wonderful. I've had almond oil that was so strong it overwhelmed what I was using it for (salad, cooking).  I loved the flavor of this oil and will be buying more.
Example Output: Positive

Example Input: This is the best tasting stevia powder I've tried. Most other powders have a weird after taste but this one doesn't. I recently bought a 5lb bag of it online and I'm making my way through it.
Example Output: Positive

Example Input: I spent close to $4.00 for each cube which turned out to be the 16oz size.  I know it says that upon further review but I was assuming it was the 3lb size because that size is $3.99 at the grocery.  And I just paid the same thing for the 1lb size?!  Shame on you Amazon.  Or better yet shame on me.  The expiration date is fast approaching too so I'm not even sure I'll use these up in a month.  I was very disappointed in the price as well as the expiration date.  I had the same issue with some sunflower seeds I bought recently, they expired before baseball season even started.  However, I did get what I paid for...it's just my mistake for not realizing the size was not what I thought I was getting.  Who would pay that for the 1lb size?
Example Output:
Negative
