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++++

I'm a little shocked that this so-called health food product is made from Chinese grown ingredients.  I'd be curious to see what the carbon footprint of each bite is.  Also keep in mind that Chinese ingredients and products have been found to have all kinds of contaminants such as lead in toys and melamine in milk and other exported food products. All the ingredients in this snack are widely available in the United States.  Why not support products and companies who source locally and consider our own economy before we sell out for a slightly cheaper price?  Your purchasing choice does make a difference.  Let's stop expecting corporations and governments to take care of our safety and economy.  They never will.  We can change the way these companies do business for the benefit of our long term health and economical well-being. Make purchase decisions wisely.

I loved wintergreen Altoids!  In fact I loved them so much I stocked up last year at Easter when they were on sale for half price.  I had enough to last until this week.  So I bought a couple of tins at my local grocery.  Today I opened one and found out 1) they are now blueish in color and 2) the taste is terrible!  What prompted Wrigley or whomever to change these?  I can't describe the taste except that it is too strong and has a bitter aftertaste - nothing like the Altoids I used to love (and I had a few left today so I could compare side-by-side).  If you love Wintergreen Altoids and haven't had the blue ones yet, don't buy them.  You will be very very disappointed.  I'm going to return the unopened tin and see if the grocery will take the opened one back too.
