Example Input: The cookies came sealed and seem to be high quality in there ingredients.  The only thing is they just don't taste that good. My girlfriend and I thought these might be a good dessert-like option while doing the Paleo diet, but after trying one of each kind over a couple days we just don't find ourselves going back for more.  I would much rather not have a dessert and really check that box on a cheat day than being left wanting more after eating these.  If you have a true gluten allergy, maybe this is a good option for you but I'm not a believer.
Example Output: 3

Example Input: I have subscribed these chips. They are so tasty. Not dry or oily. Cannot put it down once open a bag and have to have two bags in a row.
Example Output: 5

Example Input: When I got this it was melted through the package and what wasn't completely destroyed was stuck to the inside of the wrappers.  You would think that if you are going to ship chocolate in the summer time you would pack it in something cold.  I wasn't very happy with it.  I love the candy and once you peeled it off the insides of the wrappers it was good.
