(CNN) - The Better Business Bureau has issued a national alert warning consumers about a new credit card scam. The organization is urging Americans to check their credit and debit cards for unexplained charges of $9.84. Apparently thieves think they can get away with charging thousands of cards smaller amounts, instead of trying to steal larger amounts from fewer cards. The B.B.B. also says the thieves think the credit card companies won't go after such a small amount. The Bureau says if you find small, unexplained charges on your card, report it and get a new card.
