Query: Negative Stars - Seriously! ZICO? AMAZON? What are you doing?

Bought the 12 pack thinking it is a great deal. The taste is VERY VERY BAD and BITTER. I don't know what to do with the remaining 11. There is no easy method to return such grocery items on Amazon. Bought other brand from Whole Foods and tasted delicious.
