Im a current college student and have always had the luxury of paying cash for things. Well a buddy was telling me how it could be a good ideal to open a credit card or two and try to build some credit. I currently do not have a job other than being a work study at my college. Some I'm not even sure I could open one? Ideally it would be somewhere like Best Buy or Wal-mart since that is somewhere I frequently go. I would like to buy something small then turn around and pay it off before interest occurred. Would this help my credit score, or am I waisting my time and completely away from what I want to try and do.
