We love these crackers but getting them through the mail doesn't work - all the crackers were broken and crumbly.

We tried these chips because DR. OZ had recommended them on his show as a healthier potato chip alternative.  My whole family loves them, we have not found a flavor that we don't like.  These are WAY better than any baked style chip.  Try them and you won't be disappointed!

Ex Input:
This coffee is not a true medium roast like Caribou French Roast, Donut House, etc. there was not much coffee flavor at all. I found it to be so weak in flavor that not only did I have to go down a brew size, but I also have to add less milk just too drink it. I will never buy it again. Wish I didn't have 45 more cups to go thru!
