The Credit Card Act of 2009 is now in effect so consumers have some measure of protection from what many considered unethical credit practices.
Somewhat odd practices, however, are still allowed.
Walletpop has an article that lists ten things you shouldn't pay for with your credit card or it may hurt your ability to be approved for a new credit card:
- Traffic tickets
- Retreading tires
- Bargain binges
- Sex toys
- Marriage counseling
- Lottery tickets
- Cash advances
- Spa treatments and other personal indulgences
- Income taxes
