I'm watching extreme couponing, these people are nuts. They're so excited about their savings but they get so much crap since coupons are generally for junk food.
My sister does it. And to most of this extremes. When she was pregnant with my niece she fully intended on going back to work after she was born. Well long story short she didn't and sees extreme couponing as her contribution to the household finances. She gives a lot of the excess to food banks, shelters, etc. I still can't grasp how she does it though. In my mind she might as well go back to work. But it works for her.
