Best advice wasmentioned above, treat CC like you do cash. Don't spend more than you have. It's easy to get caught up in the 'minimum fee' mind set. The minimum fee will keep you chained to the CC company for a good part of your life. I know many who have learned the hard way.
Also keep in mind if you don't even want to deal with credit companies, you could get a debit card from your bank to satisfy your needs. But you don't build any credit that way. Keep your card paid off o r at the very least make MORE than your monthly payments. I try to get cards with little incentives/bonues. Like my Toy-R-US Visa gets me gift certificates to the store. Since I mainly use this as my gaming purchase card, and I'm insanely hardcore, I always have a bunch of credit to use to buy more games. Discover has excellent rewards programs as well. I'm carrying a balance on a card now because I'n saving up for my wedding, investing my money, and re-did my deductions. I usually pay this off tax and bonus time but I'm strapped this year and will kncok it down after I'm married.
Just be very careful and I'm glad you're smart enough to ask questions. I had to learn the hard way many years ago when I went to college, the companies basic give these things to students knowing darn well that they can't properly manage their finances, and that's how they hook you for life. I remember the happiness I had when I paid off, cancelled and cut my MBNA Visa (Stay the hell away from that bank). Who would've thought that I'd be paying for that order of buffalo Wings with interest for 2 years.
Be wary of retail cards as well. The interest rates are pretty high and it's easy to rack up a big balance. This is my issue with Best Buy, they have 90 days same as cash. So I had to stop myself form going in every Tuesday buying DVDs, because you can rack up pretty fast. It's easy to get out of control with those.
As you get older and earn more income and properly handle your finances, and own a home (equity), you'll be able to get anything you want. I have to turn stuff down all the time. I keep like 3 card with no balance just in case of emergency (i.e. burst hot water heater, plumbing, being sentenced to a Turkish prison), yo never know.
Sorry for the long post but I was wondering why there is really no education on the whole credit card system. I know many were lobbying for this years ago, but the CC banks shot it down. They love getting young people ignorant to nuances of the rules, and then hook them in for life.
