Example Input: Overall, the bags of popcorn were just like those that you'd get in a regular package of 8 or 12 bags.  However, several bags did not pop correctly (or at all) and had to be thrown out.  Also, many other bags would have a burnt hole after popping.  I realize that some of this variability could be due to microwave wattage, but it was only bags from this large box of Orville Redenbacher's that would do this.  I think when you order such a large box, your chances of getting "dud" bags increase...just something to keep in mind!  Is it worth it to buy in bulk when more of the bags will be duds?
Example Output: 3

Example Input: This is a close second to my all-time favorite, Jack Links Beef Steakhouse Steaks, which is the filet mignon of beef jerky. They're very similar in taste and price, but the Steakhouse edges out this one oh so slightly. Still pretty awesome jerky, very tender, and not a hint of fat or gristle. Bon appetit!

Example Input: this product comes from finland and is an all natural product that is always fresh and I have never tasted better licorice in my life.  This product arrived fast in a protective box and the price is great.  I will purchase another case now.
