"Extreme Couponing"

I'm intrigued by the show "Extreme Couponing" on TLC. These people take their couponing VERY seriously, some spending up to 20 hours a week cutting coupons, but end up paying next to nothing at the register. I admire these people's dedication to saving money, but at the same time found myself asking: Who needs 75 boxes of cereal?? I also think that some of their "stock piles" constitute borderline hoarding. With that being said... I'm sucked into the show! Check it out sometime.
