I dont have a job but i want to buy a DS lite (white) and pokemon diamond.

But i dont know how to get the money like what should i sell to GameStop or anything any ideas would be great.

P.S. My birthday has past so that sucks :( 

Steal one? j/k you could do some favors to neighbors and get some cash

If you're not underage and have good credit, apply for a DELL Preferred Account. They not only have DS's, but other gaming systems as well.

Then you can pay it off as the bills come. Otherwise, you are SOL my friend.

get a job at walmart and get a sweet %20 discount....

If you're under 16 (in most states) do various odd jobs for people.

If you're 16-17 (in most states) get a job, and fill our your minor work permission paperwork.

If you're over 18, stop mooching off society/parents and get a job.

You're just one single paycheck away from making this dream a reality!
