Example Input: We love Melitta coffee pods. Makes a perfect cup of coffee every time. The coffee is always delicious, even the decaf blend! If you have a coffee pod machine, try all of their blends...they're great!
Example Output: 5

Example Input: Not always available at our local stores. I love them. They are especially good watching football games, with you favorite malt beverage. This is a good deal, and super fast delivery, too. The nuts were fresh and tasty, as always.
Example Output: 5

Example Input: Pop Chips are the best chips I've had in a long time. I'm a Weight Watcher and to satisfy that salty craving I get now and then these chips are the ticket and they are only 2 points. And when I buy a case of them they average I think about .94. Not bad.
