Example Input: I've subscribed to receive Pamela's GF cookie mix and after the second delivery of OLD mixes I am returning to buying them in the store.  All of the last mixes during the last several months (6 bags per order x 2 = 12) have been OLD -- not expired, but the chocolate is dried up, light brown and crumbles to a powder.  I discovered it's not possible to return a subscribe 'n save order (for some reason) so I have to throw out the chocolate chips and use Ghiradelli instead.  Whenever I have bought Pamela's from Whole Foods the chocolate in the mix has been dark brown, fresh and never has crumbled to powder.  AVOID subscribe and save on this item.  Buy them in a store.

Example Input: I guess there is a reason that the ingredient section on this page doesn't mention that the first ingredient is trans fat (partially hydrogenated oil).  Had I know, I would not have purchased this.  Consumers need to vote with their dollars and avoid buying items where the manufacturer is using cheap and unhealthy ingredients.
Example Output: 1

Example Input: This product is indeed fabulous and you can get it at many grocery stores for a lesser price.  Overall a great product and makes awesome red sauce!  TO SQUISM:  I find it very disturbing that you casually refer to hitting your wife, even if you are joking, this is not the place for that sort of behavior!!!!  If you really hit your wife your a punk coward.  Domestic abuse IS NOT a laughing matter and I was personally offended by your review.  Try to maintain some amount of class when posting on here.  I am sure that is something you are incapable of doing, judging by your disgusting and classless review.
