How much will apple charge to upgrade iMac 2013 ram
I've just ordered a 21 inch iMac and I've since read that there's no user upgradable ram.
I was just wondering if anyone knows how much apple would charge to do this for me at a later date?
I phoned apple and its too late to change it before it ships and I really don't want the hassle of returning and reordering :/ I wouldn't need the increased ram until a couple years down the line anyway :)
Thanks!
iMac, OS X Mountain Lion (10.8.4)
