Buying the game for a friend?

[Ultimate Carl]

My friend's birthday is this Saturday. She's a gamer like myself, and I think she'd really like Penumbra. Hopefully as much as I do. So, I thought I'd get her Overture! Problem is, nowhere around me sells copies, and regardless, she's living a few hours away at the moment. So, is there any way I can, say, "gift" a purchase through your online store to anyone? If not, is there a simple way for me to buy it, but have her receive it?

Could I just purchase it as normal, only put her email in instead of mine but leave everything else the same?

Thanks in advance.
