Re: Best (and/or worst) place to buy manga
I work at a library and the selection is pretty bad. We have two or three volumes from about a dozen series. It is pointless to start reading them, because it is pointless. The people won't be able to finish the series by coming to the library. We do have all of Nausicaa of The Valley of Wind, so that is pretty cool.
Most of the manga I have, I got from amazon.com. It is pretty good for getting older volumes. I have many new copies of different mangas that I got for under $2.
