Teensy tip: turn your soap dish upside down so the soap is on a convex surface. Letting the water drain away will make it last three times as long. Saving your dollars can be done everywhere.
Soapdish ? That’s funny.
I was thinking a bit bigger
Another tip in the same vein:
Take all of your soap out of the wrappers when you get home.
Put it in a dry place with lots of ventilation.
The soap’s internal moisture will evaporate and it will harden and last even longer.
[or just buy “hard soaps” to begin with]
