So I'll be 18 soon. I need to establish some credit. I was thinking, could I obtain a gas card with no credit? Isn't that a type of credit card, though only good for gas? I always go to Shell gas stations, so I figure it would be worth while.
If I can get this card, I would like to pay off the balance each month. Will this still give me credit? Or do I actually need to let it sit for a month and let have interest rates screw me over in order to obtain credit?
