Save Some Green $$ - Foaming Hand Soap

I love foaming hand soap.  For years I've bought the refills that correspond with my dispensers. I recently realized that I'm paying a lot more than I need to be.  It's easy to make your own.  I now buy regular antibacterial hand soap refill. You simply fill your dispenser with about 40% soap and 40% tap water.  Then simply screw on the pump and shake to mix.  Make adjustments to the ratio of soap/water as needed. Add more water if the soap seams too thick and struggles to come out properly.
