Mining old gold -- think twice before mailing your jewelry

The ads are all over the TV and the Internet -- "Turn your gold into cash!"

All you have to do is call and they will send you an envelope to collect your "unused" jewelry and turn it into money. Some even show you how you can watch every step of the way to make sure your gold is handled "correctly."

Hang on to your jewelry box -- this may not be such a great deal.

There are hundreds of complaints registered against these companies, including Cash 4 Gold, Gold Kit and Get Gold Cash. Consumers are complaining that they have been fleeced and are sent a check for only a fraction of what the gold is worth. No kidding. It is amazing that people will simply send their jewelry trusting that they will be given a fair price. Once in the post box, you really have no control over what they will reimburse you.
