how do credit cards work?

[Romster]

One of the best things to do to build up a good credit report for you in the future for this credit card. Save the money first leave it in your checking or saving account. Then when you are ready to buy use your credit card. When bill comes you have no problems paying it off. That what I did when I was 18yrs and I am 35yrs now and still doing same thing with great results.
hope this helps..
