I love Fiber One Bran Cereal and have eaten it for many years.  Recently, I purchased another brand of high fiber cereal which resembles this General Mills cereal, but it is not the same.  I'll admit that the box I purchased this past weekend was from a brick and mortar store and the cost was half of the current price (big store sale) and it's mot an item I think of purchasing from Amazon as a single box item.  Regardless, because of the way this cereal is packaged inside the box leads me to believe that it would be a good product for shipping survival.  Years ago, a box of this cereal contained a single bag and I needed to put it in a Tupperware container to remain fresh.  It is now marketed in two packages rather than one in a single box, so I can put the single sleeve inside a glass jar after opening it and consuming the first serving.  That is smart packaging.
