MONEY-SAVING MOMENT: Groupon.com is a new site that takes the idea of Woot.com -- offering one item for sale per day for extra cheap -- and makes it local.

The service is available in major cities including New York, Los Angeles, San Francisco, Dallas, Chicago and others. Many of the daily deals are half-price offers for services, restaurants and activities specifically in metro areas. Woot, on the other hand, can be used by anybody, anywhere.

It's also different from Woot because the voucher you receive for your money can only be redeemed at a later date -- not the day of the purchase. It would be too disruptive to the restaurants and other clients on Groupon if everyone rushed in to redeem their voucher on the same day.

In addition, Groupon is a smart way for entrepreneurs to advertise their services. For example, our producer Kim operates a portable photo booth rental company for parties and events on the side. She's now considering joining up as a featured advertiser on the service.

As always, the only risk a service like Groupon presents to consumers is the possibility that a business goes bust before you can use your voucher.

Consider this: We all know Clark is no fan of gift cards -- unless you get more than you pay for. He recently bought a $125 card for $100 from a small restaurant chain. When he later tried to use it, there was a problem with the card not being activated. So he had to get his credit card statement to verify the gift card purchase for the restaurant's corporate office.
