The last thing I bought: The last thing I got was (not counting something small like "A can of Coke", not that a can of Coke is bad XD)... likely the iTunes card I got to upgrade my iPod touch. I think that's the last thing I bought.
What I'm saving up for: I have it all planned out... The next thing I want is a desk for my room, and that's going to cost around $150 or so. And after that I'm shooting for another XBox 360, this time an Elite to sit right on top of that desk (and for the time being I'll use my monitor for a TV. It's 20" so it'll do for a while). And the 360 will be around $450. And after that I plan on getting a 26" Samsung HDTV to on that desk along with that 360. And that'll cost me anywhere from $600-700 (depending on what kind of deal I can get it at).
The desk comes sometime this month or next, the 360 comes around Christmas (depending on how much money I can make XD), and the TV.... who knows. Maybe by then Erica and Robo will fully talk me out of a TV. XD
