BALTIMORE -- Imagine going to the grocery store and not only saving money, but actually getting cash back after the cashier rings up your cart of groceries.

Faye Prosser is on a mission to fill up her pantry with groceries and do it on a budget of less than $50 a week. She does it with coupons.

"If there's ever an addiction that would ever be acceptable, it would be this," Prosser said. "It would be couponing."

WBAL-TV 11 News reporter Lisa Robinson said this stay-at-home mom has turned collecting coupons into an art form.

"I'd say I have somewhere between 3,000 and 4,000 coupons," Prosser said.

She said they save her so much that there are times when the store pays her.

"They were tripling coupons," Prosser said. "My subtotal was $63.84 and they paid me $8.29 to take that home."

How does she do it? First, she makes a price list.

"A price list is simply a list of the items that your family uses, and the best price you can find them for at the stores you're willing to shop at," she said.

Prosser said a price list tells you which coupons you'll need. Because step number two is loading up on coupons -- multiple coupons for each item.

"When the item goes on sale, then I can go into the store and buy 10 of that item," she said. "And the next time it goes on sale, I'll buy another 10."

Prosser gets her coupons from the Sunday newspaper and websites like The Coupon Clippers.

"Spend maybe $5 and I may save $80 or $90 with those coupons when they've been doubled at the store," she said.

Step number three is making a weekly list of meals.

"If you're not already planning your meals in advance, I can guarantee you're spending more money than you need to eat dinner every week," Prosser said.

She makes a list of the actual items she plans to buy and grabs the circulars listing sale items.

"If you go into the store without knowing what's on sale, and what you've got coupons for, then you're going to spend more money," Prosser said.

WBAL-TV 11 News surveyed most of the major grocery stores in the Baltimore area. Most said they will double coupons valued at up to 50 cents.
