Example Input: If you like your popped corn small this is for you. Taste is good and it is crisp yet tender. The only real complaint is it has a disproportional amount of hull.
Example Output: 3

Example Input: These are decent, but if you want a realllly good salt and vinegar chip, try Boulder's Salt and Malt Vinegar chips.  THOSE are awesome.

Example Input: During my recent visit to New Orleans in June of 2012, I fell in love with Etouffee' sauce on redfish.  Oh my goodness. Delicious.  I picked up a few packages of the Louisiana Cajun Etouffee Mix, for $2.00 per package, and made it at home. It was fantastic.  I ordered the product on Amazon from a particular seller and for the price of more than 7 dollars, was delivered one package. The product description on the website did not clarify the number of packages to be delivered for this amount...I assumed three packages for that price. I received one package and returned it to them immediately.  You can purchase this product on line from the retailer for less than two dollars per package with free shipping.  So, avoid purchasing this via this seller.  Great product however.
