alright, so my cousin told me that in some cases Apple could replace your old mac with your new one, with some sort of deduction. i have the last white iMac 20", Model Identifier: iMac5,1 if that helps. i looked online and the exact one i have is being sold by Apple, on the refurbished page of apple.com for about $949. so if i brought it in to an apple store, how much would i get off? i really want a better mac.
