Sssh, TRO, don't let word get out yet. We are coming to a world of coffee mug haves and have-nots. Sad, I know, but a business opportunity for the sharp-minded.
I've been hoarding coffee cups since my pre-DW days. She doesn't understand, and so keeps trying to throw them out, but I put them back in the basement under the stairs. I'm waiting for garage sale season to top off my stash. I may need to rent a shipping container to keep them secure.
When the masses realize what's happening and start to make a "run" on coffee cups, I'll be set for retirement.
