Example Input: Love this hot chocolate--nice creamy flavor.  The price is good and I love the single packs.  This is not a flavor available to me locally.
Example Output: 5

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

Example Input: Salt tastes fine, cant say about the health claims. 3 stars is because of the packaging. The grinder top is too large for a comfortable grind. I have fairly large/strong hands and have a hard time turning the grinder. For me, when the grinder is mostly vertical to 45deg, it is difficult/impossible to grind directly onto food. Works fine if cap is left on & held in a horizontal position & them remove cap & use. The grind gives a nice fine grind (better than my OXO I also got at Amazon).
