I'm so dissapointed these are unavailable right now! I LOVE these crackers with cream cheese - it's my favorite snack! I hope they become available again soon! I can't find them anywhere!

Many reports are coming out about how chocolate is actually good for you, so eat more!  This is the perfect chocolate to do that with.  The varying levels of cocoa are perfect to help adjust your taste buds to eating dark, dark chocolate. It's not an easy transition for a milk/semi-sweet kinda gal, but this chocolate is affordable and so tasty.  I also like that I can just have one (as they are individually wrapped), and choose my %.

Had no taste and after the heat of the dish it was on turned them to a leathery tecture. Better off buying the high price truffles.
