Soap Conservation

[Old Sarge]

This might seem to some as "much to do about nothing" , but recently I have started squeezing the lather out of the brush and putting it back into the container. As expensive as some soaps can be, I figure this is an easy and practical routine. Thoughts? 

I also squeeze the lather out of the brush, but I use it for a post shave face wash. I generally don't rinse out the soap container and only wipe down the outside and top edge then set it aside to dry out for a few hours, so some of the lather would dry out for the next shave. It seems like most of these soaps will take a long time to empty out and aren't we all looking around and thinking of buying the next new soap?
