It's mildly interesting. Here's one paragraph. "A study by NCH Marketing Services, an Illinois-based coupon clearinghouse, found that the percentage of regular coupon users in America has dropped to 21 percent in 2001, from 22 percent in 2000 and 25 percent in 1999. Only 51 percent of consumers agree that coupons "save them a lot of money." And, of the 239 billion coupons distributed by the consumer packaged goods industry in 2001, only 4 billion were redeemed - a significant 11 percent drop."
