Dude, when I was a teenager I had to buy everything XD. Had a job through all of high school; worked weekends, some evenings and all summer. PS2? Making 6 bucks an hour, it takes forever to save for one of those things...hoo ha.
I know I sound like an old fart who swings his cane around going, 'Back my my daaaay!' But half my friends had jobs either babysitting, delivering papers, tending lawns/cutting grass, etc. before they even hit the age of 15. I'm an advocate of, 'If you want it really badly, find a way to get it'. Even if you gotta borrow someone 18+ for it, you can get prepaid, single-use credit cards to buy stuff online. I believe in you, padawan.
