The Better Business Bureau wants to warn you about a scam involving re-loadable prepaid money cards.
BBB officials say Green Dot Moneypak cars are hard to trace and don't require a photo ID to retrieve funds.
There are various ways a con-artist can get you to buy one of these cards.
For example, a scammer might tell you you've won a sweepstakes, but the BBB say that should be a warning sign.
“Basically when it comes to the sweepstakes types of scams and things you should never have to pay anyone a dime in advance of receiving your winnings,” said Monica Horton, BBB president.
Once you have bought one of the cards scammers will ask you to give them the information from the card so they can use the money immediately.
The Better Business Bureau says the best thing to do is investigate when someone asks you to purchase one of the cards.
