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

The first box/12 pack i ordered seemed not as crisp as what i had purchased in a store. But the next box was clearly uncrunchey, stale, soggy tasting. I see 2003 mentioned on the packages. Although i very much like the product normally, i'd be afraid to order it from Amazon again, as there are no returns on foods. I couldn't find an Amazon address for complaints, which is why i'm doing the review. The product obviously sat too long in someones warehouse.  Amazon quickly replaced my order with a box of fresh crunchy crunchitos. Very good. I'll probably order again.

Ex Output:

Negative
