Some people will do just about anything to save money. And I am one of them my family’s last vacation was my six-year-old son’s winter break from school, and we were heading home from Fort Lauderdale after a week long trip. 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 encouraged一okay, 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 some-time thing few of us can afford to pass up.
I've made living looking for the best deals and exposing (揭露) 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.
