Frugal Family Challenge: Can these parents trim expenses?

— -- Most of us know we should save more, shop less and live within our means. But temptations to spend beckon to us everywhere.

Fact is, millions of American families have saved little or nothing for retirement, college or emergencies.

So in conjunction with ABC's Good Morning America Weekend, USA TODAY has created the Frugal Family Challenge. With help from a financial planner, two participating families will spend 30 days trying to shore up their finances.

In this month's challenge, Jennifer and Bruce Pivnick of Richardson, Texas, and Jimmie and Mitzi Walker of New Haven, Mich., will try to live within a spending plan. We'll revisit the two families at the end of the challenge to see if they met their goals.

In the meantime, you can follow their progress at www.abcnews.com. Search for " Frugal Family Challenge."
