There are a couple benefits to a credit card as long as you are paying them off and not using them when you don't actually have the money to pay them off.

• It can improve your credit score which is important if you ever plan on buying a house, so you can get a loan.

-There usually aren't any fees for using the card like most debit cards have (at least where I live).

• many credit cards offer a reward system which you can use to get free stuff, or sometimes just cash back. I have a dividends and get a percentage back on every purchase up to a maximum.

So as long as you pay them off monthly, using a CC instead of debit can actually save you money and be a good thing. It's when you can't pay them off, and instead just meet the minimum payments that they become a problem since they have crazy interest rates.
