Holy smokes! Take that offer. I checked what they would give me for a perfect condition 2008 aluminum Macbook (which I own) and the offer was $278! Take the money!
I plugged in your specs just to see what they'd offer, and their offer to me on a machine with your specs was $451...
Either way I am happy but what the heck?? $451??? You are referring to my post right? haha
