I've become addicted to coconut water.  It's an expensive habit, so when it goes on sale, I stock up.  Vita Coco coconut water is on sale at Amazon — 15% off, or 30% off when you use "subscribe and save" a subscription shipping program that you can cancel as soon as your first order ships.  It's a great deal — but hurry — it expires on December 31st.  Pick up a 12 pack of 11.2 oz boxes for $17.85 with free shipping at Amazon.com.
