I’ve given up on keeping Tupperware containers in space-saving arrangements with their lids stacked separately. The great Tupperware-bottom towers always collapse and fall out of the cabinet, and I can never find the right lid.
I’m willing to use the necessary amount of space to keep all of my Tupperware and Tupperware-like imitation containers closed with their proper lids and stacked normally all the time.
My 25-year-long frustration with the Tupperware cabinet has now ended, and it’s wonderful.
