I bought these for my son to take to work for lunch. Apparently his co-workers found the smell so offensive they asked him not to eat it at work again. Maybe it was a bad batch...

I've read the reviews and I agree that Yuban is absolutely the best coffee but at $100 for 12 cans comes to over $8 a can.  That's $3 more a can than I pay at my local store.  I don't understand the high price?

I have been Gluten Free Since 2003 and this is I think the worst tasting GF mix I have come across. I have found all to have their own pros and cons but this one have very little to brag about. I appreciate the effort anyone puts into a GF product but I couldn't buy this one again. It was like eating reconstituted potatoes that lookes like pancakes. No butter or gravy, just dehydrated spuds. The only real good thing to speak of was the texture. It was light and moist but I would have to seriously alter the recipe to add flavor.
