Example Input: Was looking forward to this drink but was put off by its sweet soda-like taste.  Maybe it's an acquired taste? I'm not sure  but the high calories don't make me want to try.  Looking forward to a diet version.
Example Output: 2

Example Input: I used to order this product at 25 per box of 12 cans and now it turned into 50 dollars??? how did it double out of nowhere??
Example Output: 1

Example Input: I found this exact same stuff at the dollar store.  It is pretty good.  Not as good or as strong as my loose whole leaf tea, but for the price it can't be beat. Bags are never as good as loose leaf.  I use it if I want one quick cup.  I steep my loose leaf tea 2-3 times, so I have to have time to drink 2-3 cups.  I gave this 4 stars because it is a good deal for the money purchased from the dollar store. If I make myself a mug, and because it is cheap, I use 2 bags.  I would have been disappointed if I had paid the original price on here for it though.
Example Output:
