Example Input: I am fairly certain this is the same tea sold by Caribou Coffee.  I think I could be considered an addict! The flavor is so good - lots of cinnamon and slightly spicy because of it.  Price for 50 is good and less than I have been able to find it elsewhere.
Example Output: 5

Example Input: I received the items in a timely manner. Upon receipt, I removed a pack to consume. The pop-tart was STALE and left an awful taste in my mouth.
Example Output: 1

Example Input: This tea is absolutely incredible! Addicted after first taste. So delicious... the smell... the taste... it's a beautiful experience. I just ordered more (and gonna try both regular and decaf).
