Example Input: Due to health issues, my husband is newly required to eat a gluten free diet. He acted as if he was on death row. Finding this product has help immensely. I can make him pancakes with fresh fruit and he doesn't feel he is being unfairly punished. Also, my neighbor was faced with a similar circumstance. I shared one of the boxes with her and she is now a fan! <a href="http://www.amazon.com/gp/product/B004391DK0">Bisquick Pancake and Baking Mix, Gluten-Free, 16-Ounce Boxes (Pack of 3)</a>
Example Output: 4

Example Input: I bought these for my boyfriend who really likes honey roasted pecans in salads that I have at a couple of restaurants. Plus, he likes nuts, pecans, almonds peanuts. He loved these. I actually ordered 3 cans instead of the gift tin, so he could take one to work, or his place, and stay fresh longer. Although I don't think freshness will be an issue, they won't last long......lol
