Just saw this today, I'm pretty sure it's new:
http://ebookstore.sony.com/gift-center/
If you have the eBook Library you can send someone else eBook Library gift certificates.
I know a lot of you don't like the ebookstore, but for those who do, I think it might be cool to use this in the Flea Market. Like for example, if I wanted to unload pbooks, and you wanted them, you pay so much in ebook certificates.
What do you guys think (I don't have pbooks to get rid of, that was just an example
)
