Consumers are flocking to a wave of new classes at community colleges and libraries that show them how to use coupons to save on their grocery bills.

They're searching for coupons online, and they're signing on to one of about 2,000 so-called mommy blogs that pair manufacturer's coupons with items on sale.

Coupon clipping has surged in popularity, and it's not just because of the economy. The increase also has to do with more access to savings -- everything from blogs to smartphones -- and the popularity of a reality TV show.

"For many people, couponing has gone from a responsible way to save money to a really fun game," said Stephanie Nelson, founder of CouponMom.com, a website dedicated to couponing.

Nelson said much of the buzz over couponing was stirred by the TLC network's "Extreme Couponing" show, which follows shoppers such as St. Louisan Rebecca Routson, who bought $562 worth of groceries for $25.91 at Shop 'n Save. "Couponing has actually become an interesting television topic, and because it's entertaining and so extreme, it makes people curious," Nelson said.

The day the pilot of "Extreme Couponing" aired on Dec. 29, 2010, Nelson said, she saw a spike in traffic to her site and an increase every time an episode ran. CouponMom.com has 5.5 million members and gets 210,000 hits a day, Nelson said.

Dustin P. Smith, a spokesman for TLC, called the ratings for "Extreme Couponing" very strong. The network recently debuted a spin-off, "Extreme Couponing All-Stars." The show pits past cast members in a head-to-head competition.

"We've seen an amazing response from the community and media covering people saving money and this couponing renaissance," he said.

Local community college educators say that some of the most popular new offerings are classes about couponing. At Southwest Illinois College in Belleville, three couponing classes were slated this past fall, with each class comprising three sessions. Several sessions have also been added at St. Louis and St. Charles community colleges.

On a recent Saturday, 21 women ranging from young mothers to grandmothers gathered at St. Charles Community College to get couponing tips from Routson, who was on the TLC show in April.

She gave a PowerPoint presentation about coupon lingo and described different types of coupons. She files her coupon circulars by the date they come out but doesn't clip them until she's ready to buy an item; otherwise, she said she'd have little time for anything else. Routson and her boyfriend have a monthly grocery budget of just $50.

After the TV show aired, Routson said, she has had multiple requests to share what she knows about couponing. "I had never planned to teach, but people really want to learn about it," she said. "I know how much it helped me, so I couldn't say no."

James Fisher, chairman of the marketing department at St. Louis University, said another big reason for the growth in coupons was because of the mobile mechanisms that deliver them now.

"You can get coupons delivered to your smartphone, take it into a retail store and they can actually scan the coupon from your phone," he said. "The Internet can help you find coupons that fit your own timing and purchase cycle as well."
