The Perils of Extreme Couponing

I've often wondered if these people were urban myths: The people who never buy anything without a coupon. People who save so much money they brag that stores are paying them to shop. People who have a lifetime supply of toilet paper or will never need to pay for toothpaste again.

Now, we can all watch "Extreme Couponing" on Discovery's TLC. It's informative -- lot's of good hints on how save bundles -- and terrifying, a cautionary tale of obsession. The show profiles four coupon-obsessed shoppers and Walletpop spoke to two of them prior to the show's premiere tonight.
