The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meeting in New York,So I had to get back . But that didn't mean my husband and my son couldn't stay. I took my nine-month-old and took off for home. The next day my husband and son were offered more credits to take an even later flight. Yes, I encouragedokay, ordered-them to wait it out at the airport, to "earn" more Delta Dollars. Our total take: $1,600. Not bad, huh? Now some people may think I'm a bad mother and not such a great wife either. But as a big-time bargain hunter, I know the value of a dollar. And these days, a good deal is something few of us can afford to pass up. I've made living looking for the best deals and exposing the worst tricks . I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in. I tell you this because there is no shame in getting your money's worth. I'm also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate to spend on a good haircut. It keeps its longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts. Question: Why did Delta give the author's family credits? Answer:
