I baught this kind of cereal from Wholefood. Since this was the first time I tried this brand, I picked 3 kinds: multi-grain, oatmeal and brown rice. Oatmeal was all right, but the other two smelled like they were already stale(the expiration day is May 2013), and they tasted bad too and sticked on my throat when I tried them. My baby cried and refused to eat them. The customer service of Wholefood was very nice and refunded me. I don't think I will buy this brand of cereal again.

Ex Output:
Negative

Not sure if I'm supposed to write this but the first shipment I received was all expired. Customer service was happy to send me a new shipment with no problems. So make sure you check the expiration date when you get it. Secondly, I love the fact that Back to Nature has made the attempt of an all natural pasta. I've been looking for something to replace Hamburger Helpers since their ingredients are less favorable. Unfortunately, the overall taste and texture of this product is not good. It has a "tang" as an aftertaste and the texture is always bumpy and not creamy. My kids who are 4 and 2 will not eat this. And they are not picky eaters. Sadly, I have 10 boxes left. I will just use the pasta and throw out the sauce package. I suggest you find this at the store and try it first before you buy the case.
