Example Input: I bought 21 0z freeze dried liver. Half the container was filled with powder instead of pieces/chunks. I feel I was betrayed by the company. Hence I did not get what I paid for
Example Output: 3

Example Input: Not one member of my family, including me, like these extremely salty, much too strong a BQ taste to order more. I purchased them on a recuring basis and i wish to cancel now. I have received only one shipment. Cancel further shipments. Not to our taste at all. These are Lowery pork rinds.
Example Output: 2

Example Input: I recently tried this line of breads on vacation and loved the one we tried. I couldn't find the European Cheese & Herb flavor that we had locally so I went to order from Amazon.com. As happens from time to time the seller was out of that flavor so I picked up the Potato Bread instead and it was also very good. I still need to get the Cheese & Herb because that one was awesome.
Example Output:
