Query: Be careful, some packages were moldy.

Two stars because I've had this product before from the store and it is fantastic and very healthy. However when I thought I was getting a great deal from Amazon, it turns out that when it arrived, half of the bags were moldy! However, Amazon was great about it and refunded my money. Perhaps the lack of preservatives give them a very low shelf life, so if it's low in sodium, consider buying from a local store when you can check the package and dates before buying.
