it happens like this: i got a good deal on a 3-month-old MB (core duo) from my neighbour who's leaving the country for good. so i bought it - even though i already have a MBP (core 2 duo) and a MP. i checked it thoroughly and paid money. 1 month later (today) my GF wants to get it, so i wanted to do a fresh install, so i realized that i forgot to ask for the OSX CDs. it's impossible to get them now because the guy's already gone. so, is it possible to get another copy of it (say, from Apple)? or do i have to buy a new one?
