Ex Input:
These potato chips are DELICIOUS!  I have not had potato chips in approximately two years as it has been difficult to find organic chips.  Amazon lowered the price on these, and I finally had a chance to order them.  I most definitely will be ordering them again!  My family and I love them.  They are pure and void of all artificial flavorings.  The true flavor is present, and it satisifies the need for something salty, sweet, spicy, and crunchy.  A++++

Ex Input:
I love, and use the empty containers for medicine/advil in my purse, desk, suitcase. Also line with felt to keep earrings. Perfect little size to disguise small valuables when traveling and LOVE the mints. Tiny and powerful without burning my mouth.

Ex Input:
The entire family loved this pancake mix. It was easy to make and tasted great. We tried it with syrup, powdered sugar, as well as fresh strawberries and apple compote. I would definately purchase this again. The only problem is my family wants this every weekend and I have to double to feed my large family. It gets expensive quickly, so I do not order it as often as they would like.
