ebook

Does anybody know where I can get my hands of the entire Buffy & Angel ebook collection? I know that a few years ago they officially re-released a few in that format but then stopped. I would love to have the entire collection on my ereader.

Seen as it is looking very unlikely that the entire collection of Buffy & Angel books will ever be released on ebook format is there anywhere that I can look to find these or do any of you guys have them in ebook format? I know Amazon has a few but not many.
