Soap Shredder

I love stuff like this. An easy way to do something more efficiently (and with less impact) that you're doing anyway. Liquid soap is a HUGE waste of money, mostly because what you're buying is about 75% water anyway. This device shreds a solid bar of cheap, traditional soap into flakes on the fly. That allows for more surface area, more surface area means easier lathering, which means less soap needed.
