The art of extreme couponing—or collecting web, newspaper and even mail-order coupons and combining them with in-store deals and rewards cards to cut grocery bills by upwards of 100 percent—has obvious perks. There’s security in knowing you could stop shopping and live off your stockpile of groceries and household supplies for a year. Who wouldn’t want to own enough Vitamin Water to fill a pool? But there’s a downside, too—and not just for the kids whose mothers are stashing ungodly amounts of Cheerios under their beds or the people stuck in line behind couponers at the grocery store. With the success of TLC show Extreme Couponing, people are starting to pay more attention to the coupons they once threw away. They’re bitching more when they aren’t saving what they want to and, as a big-box store employee recently told me, making everyone in customer service hate their jobs even more than normal. So, hey, people, let’s leave the extreme couponing to the professionals—and by professionals, I mean the housewives digging through other people’s recycling bins. That’s pretty extreme.
