What are the best ways of obtaining credit ?

I have no credit card, don't make much $ but am very good @ saving up $. What should I do ? Should I save a few hundred dollars & then ask the bank to lend me the $ & then pay them back in a certain amount of time ? I'd like to have a credit card to be able to buy tickets online or even through ticketmaster. I'd ONLY use it for concert tix. What's the best way to go about in doing that ?
