I'm a librarian who loves anime, manga, and reading a wide variety of genres.
My TBR Thursday post this week is going to be embarrassing - I bought so many things from Samhain yesterday. It mostly went well, except for one e-book that Calibre claims has DRM. The last time I had that problem, Samhain customer support had to email me a usable file. I emailed them about the book, but who knows how much customer support staff they still have.
ETA: When I got off work, I saw I had an email from Samhain. They sent me new files. The epub version had the same issue as before, but the mobi version opened just fine. I converted it to epub and it looks good, so I consider this a success.
