Exreme Couponing show on TLC

I don't know how many of you out there are aware of this show, but there is a new show on TLC called Extreme Couponing.  I watched the first of two episodes last night, but was turned off by the second episode.  It's just strange that they show us these people who are capable of getting $600 worth of groceries for $6 but they don't show us HOW.  I wish they would show us HOW!!! Either they  need to expand on what these women are doing or something.  I follow several blogs of other women who are coupon clipping and doing similar things to what the people on this show are doing.
