I have a copy of Leopard that I bought at my university's book store for $99 for a friends "Mac." Turns out he wanted to install it on a G3 iMac, so now I'm stuck with it. It came in a brown envelope with the MB432ZM/A part number on it (Leopard retail part no.). It is the disc and license agreement booklet, which I read, and is a plain single user license. I'll let it go for what I paid, $100, shipped. If you have any questions, send me an email.
oh yeah, feedback on ebay under tristalynn123, heatware under hookem2oo7 though i think there's only one or two on there.
