My dog thinks he was born into the gentry and is entitled to fine dining each evening.  Accordingly, he will not eat plain kibble.  A scoop of this on his dry food, a little water to make gravy and we're good to go.  Ordering a case from Amazon was way easier than picking up individual cans at the pet store, too.  All in all, a success for us.

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.

All of the Castellana pastas are absolutely wonderful.  They have a great taste, hold their unique shapes, grab lots of sauce in your dishes, and have a nice "bite."  This is a great price for this item!
