Example Input: I have had waffles from other mixes that are too sweet.  I have also made them from scratch. I like my waffles with NO Sugar in them, because I don't like too much sugar.  This mix is very good.  Waffles are just the right consitancy for me and the mix is easy to prepare.
Example Output: 4

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 Output: 2
