TwinqeWere you planing on paying for one in-store (Do not do this) with just cash? If you buy from anywhere online (You should do that) you will need some sort of credit or debit card. If you're too young then you will need to ask for your parents' help, but I don't see why that would be an issue anyway as if you don't own a credit card in the first place then you're not likely paying for it.
Lenovo laptops are also fairly cheap and pretty good gaming laptops, if you must have a laptop.

Even if I was a child I don't think I'd ever ask my mother for help. She criticizes me for everything I do. I am paying for it but not with credit card. I'm going to be using my college card with works similar to such or a debit card. I thank you for the help!
