Frugal Quick Tip: Save Money On Water Bill

I recently read this in a Redbook Magazine, I haven't tried this trick and don't know if it's safe for the toilet.  Now that I got my little disclaimer out there, I will tell you the money saving idea... :)

To reduce water usage, fill a half gallon milk jug with water and pebbles to weigh it down, and place it (capped) into your toilet's tank.  According to Redbook, "a family of four could conserve about 16 gallons of water a day."  Their calculations estimate that would translate into about $90 of savings a year!
