Sob!Sob! Sob! Years ago Tupperware made ideal cereal containers which had flat tops on them which enabled them to be stacked in a cabinet. Some of mine are no longer useful, so I wrote the company and talked to a rep, but they no longer make them, even with multiple requests from other customers. Sometimes when things work so well, why must the manufacturers change them? That old saying "if it ain't broke, don't fix it" must not appeal to younger folks.
