My store doubles up to $1.00 coupons meaning unline other stores, they will double .75c for a $1.50 off discount. Then you can stack it with a store issued coupon often getting the item for cents on the dollar.
As far as it hurting the economy, it doesn't. It keeps people buying brand name products - the company's incentive to keep sales up - so it generates business for the manufactuer. The stores are reimbursed face value (sometimes doubled) plus .8c handling fee per coupon. So it's not hurting the store either.
These people on the show are extreme. These scenarios piss every day couponers off because it makes stores have stricter coupon policies that actually slow things down at the register. Most people I've seen who use coupons are organized and don't argue and don't want to inconvenience other people.
I databased my savings the first 3 months of this year. I saved an average of 40% off my household shopping - $250-$300 per month. The only money I spend is $5 a month for the newspaper and printer ink and paper every few months.
