I have been buying ONE Coconut Water with a Splash of Pineapple regularly for awhile now. I like the flavor and ordering it on line is very convenient. Also, I have had no problems with delivery.  Unfortunately, IPROZON has just lost my business.  I didn't mind paying $15.00 for a case of 12.  I will not, however, pay $39.95 for a case of 12.  That is robbery.  I can walk into Fred Meyer Grocery and buy a case of 12 for $17.88.  Plus there are other sites still selling it for $15.00 per case.  I noticed IPROZON is still selling the other flavors of ONE coconut water for $15.00 for a case of 12.  So what on earth are they thinking.  I am quite unhappy with having to trust one of these other sites with my credit card information, but I am willing to do that versus paying nearly $40 for a case of 12.  Quite ridiculous.

I regularly purchase this item in the bulk and loved it because it was also dairy free. However, my last purchase was disappointing, after opening a brand new package I noticed a black thing in the mix, carefully removed to find out it was a dead flour beetle! I sifted the mix and found more DEAD BUGS!  This is the second time I writing this review. Amazon didn't publish my first review. Thank you AMAZON. I will not be purchasing this item again.

These are the strongest tasting salt and vinegar chips I've had.  I could still do with more vinegar flavor, but I think this is as close as I'm going to get without dousing them with vinegar powder myself.  I did a side by side with the Cape Cod salt and vinegar and these are about twice as flavorful.  Additionally, as other reviewers have said, they have quite a good bit of potassium in them (somewhere in the neighbor of 15% RDA per serving).
