Input: Consider 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++++

Input: Consider Input: The only reason for the 3 stars was the packets the individual teas were in.  I love this tea, I have the ones in the tin on auto delivery.  I was taking a trip, and ordered these so I could take some with me on my trip.  Prior to leaving home I took some out of the box and put them in my suitcase.  I got to the hotel and tried to open the little packages.  Impossible to open the individual packages.  No knife with me, I ended up using a toe nail clipper to open the individual packages of each tea.  Hopefully this was just a problem with the first box, but I would not recommend buying this tea in the boxes, go for the cannisters.  If you do buy the boxes have something near by to open each and every packet of tea.

Input: Consider Input: This brand of granola bars are really good.  The very berry are my favorite.  However, the bars are almost ridiculously small.  Yeah, we're gluten free, so our food is a lot more dense than other food, but honestly, can we not have normal sized, good tasting granola bars?  They really are tiny.  So, the taste is GREAT but the bar is small.
