What should I buy???

I just had a birthday and graduated 8th grade so I have a lot of money but don't know what to buy. I like movies so i was thinking of getting some dvds. Can u reccomend any movies like alpha dog, the outsiders, scarface, pulp fiction, resivour dogs, goodfellas, taxi driver, rocky, dazed and confused, boondock saints. Also, i was thinking about buying some tv shows so anything like freaks and geeks, undeclared, workohoholics, that 70s show.
