My husband and I actually tried this. We left our cards at home and used cash everywhere we went. We didn't spend as much because if we were out of cash, we couldn't get anything. It's a good challenge. I think everyone should try it out and see if it makes a difference in your spending.

The good and the bad thing about credit cards is that they are very convenient. It is hard to really tell how much you are spending until you get your bill or statement each month.
