The taste is great but most of the crackers are broken.  I am maybe getting 12 whole crackers per box.  The first time I ordered these there were several broken but this time there are more broken than whole.

I have this on auto ship because I use it so much. I have gone to every grocery in AZ and the cheapest place is Amazon! This is a great product and whatever you make using this flour will taste great. My son has Celiac and is allergic to gluten. I have tried every pancake mix and this one is the one I settled for!

Ex Output:
5


Ex Input:
These cups are artifically sweetened with sucralose - I didn't realize until I tried one, and ended up with a little bit of a headache, which made me check the ingredient list - it isn't noted on the front of the box.  They definitely have an artificial taste, I would not buy them again.
