Example Output: 5

Example Input: Soon as I got this bag of decaf I made a big mug and it filled my house with the wonderful aroma of high quality fresh brewed coffee.  It is very finely ground but I still used the same amount I normally do and it turned out great.  I added some soy milk, sat back, and enjoyed my rare treat of an after-noon coffee break!!!  Definitely will buy some of this for the winter months so I can treat myself to excellent hot coffee any time of the day or night!
Example Output: 5

Example Input: a $5000.00 diamond would be cheaper to ship than a $5000.00 car!  I don't buy from any supplier that ships by price. This item is $7.95 then you pay $11.95 for up to $20.00 for shipping? No way I would pay that for one jar.
Example Output:
