Oh really? Underage?
Don't have any relatives or family that has an ebay and PayPal account?
Trust me, its the best way... you'd be doing yourself a favour.

By the way, heard of the Nvidia Shield?
It lasts for ages, very powerful, its also the ultimate portable gaming console.
I saw it used for about $150, and brand new for $200.

Say, can you use Amazon?
There's some good deals on there, but not as competitive as ebay obviously.
