Trade-up policies?

[thermodynamic]

I bought an iMac (24", early 2009 model) in April to help with school work. (and I was tired of Microsoft Problems(tm).)

By the time I graduate, or sooner if I let greed get to me, I'll want to upgrade to a Mac Pro.

Are there trade-up programs where I could get a bit of money back from the iMac I had purchased?

Thx!

Not officially through Apple that I know of, but there's always craigslist and if that fails, perhaps e-bay? I'm currently trying to unload my old PC desktop that way.
