A San Antonio woman is helping people of all walks of life save money at the grocery store, one coupon at a time.

Brenda Anz calls herself a "coupon educator." "I teach coupon classes, and I've been doing it for the last 15 years," Anz said.

"So I come into the household, and I help them learn how to save by using more coupons and less cash at the register." Through in-person and online classes, Anz believes she has helped tens of thousands of people learn how to make their money go further.
