Tuxgames (
http://www.tuxgames.com/details.cgi?&gameref=138) sell it in the UK priced at $55 (without shipping if I remember correctly) ,
BUT they took a long time to ship the game. Some still haven't recieved it, and their website shows it as "temporarily sold out".
I hate to recommend them after all the time they made me wait and their poor customer service, but if your friend isn't in a hurry it could be an option...
