Dirty Little Spending Secrets

      Money is one of the top things many couples disagree about. And, according to a new study, many spouses are secretly spending without telling the each other.

      So how much is appropriate to spend on a big ticket purchase without telling your spouse? According to an Experian survey, men gave a dollar figure about three times the amount that women gave.

      On average, men said they would spend about $1,200 before talking to their spouse first. Women said they wouldn't spend more than $400.

      Researchers say, that could explain why money is such a flash point in so many marriages.

      A study by Utah State University last year found that fights over money are the top predictor of divorce.
