Query: great cereal!

I discovered this cereal at a local market and was thrilled. I have a mild allergy to wheat and try to avoid it when possible. Corn Crunch-Ems make it possible for me to eat cereal -- plus I like the taste. However, my local store stopped carrying it. Thanks, Amazon, for having it in stock -- and at a great price.
