WYLIE (CBSDFW.COM) – A North Texas woman, who has a passion for collecting coupons, is working hard for others. But when Tina Klein learned she was getting a lot of items basically for free, she had to decide what to do with all the food she collected.

Klein takes grocery shopping seriously and when she shops with coupons she doesn’t stray from her list. “I live, breathe and sleep coupons… probably at least 10 hours a week,” she said.

Klein says she learned how to save a lot of money at the grocery store and the drug store when she started to study the coupon method described at couponmom.com website.

Her shopping trips are often successful because Klein also learned to collect coupons for items that are on sale. “It’s on sale for 88-cents and there’s a 50-cent coupon and Kroger doubles up to 50-cents,” she said of one deodorant coupon opportunity.

Klein also finds out, in advance, which coupons to expect when she checks out. These are called “catalinas” or the coupons printed at checkout, that are good on your next shopping trip.

It takes work and careful calculations, but on one shopping excursion Klein paid just over $8.00 for $68.00 worth of merchandise.

Klein has three daughters. Over time she became so good at collecting coupons that she now buys more than her family needs at home.

The North Texas mom acquired so much free, or deeply discounted, food that she’s now donating it to the food bank at the Wylie Christian Care Center.

“I just never met anybody like her and she’s had problems herself and she still works to help somebody else,” said Food Bank Director Kathleen Moore.

Moore is right, Klein has had her share of issues. In fact, about 10 years ago, when her daughters were young and Klein was going through a divorce, she went to the Wylie Christian Care Center for help. “This is a great way to give back,” she says.

Recently Klein launched her own website, supercouponwoman.com, and calculates that she spent $75 for the $1,025 worth of food and notions she delivered to the food pantry Thursday.

“There’s a lot of people struggling. There’s a lot of people losing their jobs. The food pantries are down,” says Klein.

Klein delivered more than 500 items to the food bank and now hopes other people will follow suit, shop with coupons and give the extra to local food banks. There’s also a box filled with coupons at the food pantry.
