I love these crackers!  Perfect snack for when I need something salty/crunchy instead of potato chips or other greasy snack.  I eat them a lot to hold me over between meals.  The price on amazon is great compared to my local markets.  Highly recommended!

Bought these for a birthday and they were perfect--all arrived uncracked and wrapped really well. Super cute and perfect for 4 year olds.

I ordered this for my birthday. I got birthday money from family, and I ordered a couple of goodies, perfume, and this cocoa.  I love hot chocolate, and I'm always looking for new ones to try.  Based on the first review I decided to go ahead and order.  I will probably not reorder.  Mixed by itself into hot water it seems to lack thickness.  It also has too much of an artificial raspberry taste.  I like Hershey's Bliss Raspberry Chocolate much better.  I've been adding one spoonful of the Cobblestone Kitchen to my regular cocoa to give it a raspberry boost.  But, by itself, it does not stand up to the test. I plan on finishing the three remaining cans over time by using it as a stir in additive to other cocoa.
