My girlfriend isnt as extreme as those guys but she uses coupons from the sunday paper when she it matches something on her list.
She told me that because of this new interest in it, some of the stores that were offering stacking coupons are now stopping. Most of these people that bought 300 bucks worth of groceries for 10 bucks would stack coupons then use their store benefit card for it to work.
heres one article about the kroger stores.
