Of the 12 cans shipped 11 of them had very, very serious dents in them. I'm not talking dings, I talking serious dents.  So dented that I truly thought of throwing them away.  My husband stopped me though because at $5 a can he felt that it was too wasteful.  In my local grocery store, items this dented are put into a reduced price bin, because they usually don't move otherwise.<a href="http://www.amazon.com/gp/product/B002C4HZ00">Cento San Marzano Certified Tomatoes, 28-Ounce Cans (Pack of 12)</a>

I am very pleased with this selection.  I have not tried the other hot cocoa brands for Keurig but this one is awesome!  I bought the milk chocolate.

I've always wanted to like coconut water - low in calories, high in minerals - but I've just never liked the taste much. The pineapple juice in this really makes a difference. It still needs to be well chilled to be good, but it makes a healthy post-workout drink.
