Nowadays I see 5000 varieties of oatmeal on the shelf, but some of the other hot cereals that use to be can only be gotten on-line such as Maltex or Cracked Wheat cereal, which I now have to buy on-line by the case (6 boxes) and freeze so that they stay and don't spoil.
And even buying them by the case doesn't make them cheap especially when adding in shipping, by any stretch of the imagination.
