this is a really interesting article. I had never heard the term "Extreme Couponing" but I guess I am one of them. Lol! Here is the most interesting part:
Fueling the increase isn't the general populace but heavy coupon users, people who redeem 104 or more coupons over six months, according to an August report by The Nielsen Co. These users tend to be females under the age of 54 with college degrees and household incomes above $70,000, Nielsen says.
Hmm...Couponers are generally young, educated, savvy, middle class women. Didn't we already know that? :)
