Ex Input:
I was excited to see that Amazon is selling 100% Kopi Luwak. However, these beans were a huge disappointment because they had no aroma and flavor at all. I'm guessing that they sent stale beans because there was no roast date printed on the bag.

Ex Output:
Negative


Ex Input:
I have had waffles from other mixes that are too sweet.  I have also made them from scratch. I like my waffles with NO Sugar in them, because I don't like too much sugar.  This mix is very good.  Waffles are just the right consitancy for me and the mix is easy to prepare.

Ex Output:
Positive


Ex Input:
I wait for this cereal to go on sale before I buy it and the sale price is usually $1.99 per 12 ounce box.  The regular price is about $4.  $28.88 for 70 small boxes of less than one ounce each is 41 cents per box/nearly per ounce. The sale price is 17 cents per ounce.  The regular price is 33 cents per ounce.  On the other hand, this should make two rice krispie treats with one box.  Starbucks sells rice krispie treats for $2 as one of their lowest priced snacks.

Ex Output:

Negative
