I admit that I fully expected to dislike this product, and approached it with a dismissive attitude - something that's this trendy can't be any good, right? well, I was wrong. The ONE coconut water is refreshing, delicious, and just barely sweet. Really wonderful stuff. The hint of pineapple adds a little bit of acidity that enhances the basic taste of the water. i bet this would make a great summer drink too, but I only had one so I didn't get tot try that. My problem now is that it's been out of stock, so I can't get more.

Like I said about the icing....I am so happy to be able to buy this online. It is a family favorite, it also was shipped on time and arrived early. Definitely going to buy again.

My two cats love this cat food more than the kirkland signature brand.  It's also very cheap and affordable cat food at walmart. I would recommend this cat food over meow mix or friskies any day.  Get 9lives dry cat food.  It's one of the better brands out there.
