I found these 16.9oz O.N.E. coconut waters for three for 99 cents at one of the 99 Cents Only stores in Ventura yesterday. If you have a dollar store near you, you should definitely stop by and see if they have any in stock. This is an amazing deal!
As I've mentioned before, I have a pesky neuro disorder for which I find loading up on potassium very helpful. In fact, I drink like three of these every day, so you can imagine how expensive that can get. Fortunately, I have had great luck finding these great deals at dollar stores and stocking up on cheap coconut water ever time I do (I bought 40 this time!).
I also use them in the potassium-packed smoothies I make a few times each week.
They are not always in stock, so get to your local dollar store soon to see if they have any!
