They recently added a decent sized book section the Best Buy I work at, as part of Media, my section. We have two bays of manga, which is two four foot wide shelves of books, about six feet high.
And it's in the corner, so there's about twelve square feet of space in the "manga section".
As soon as we put it in, the fucking narutards and fat, ugly bitches fucking set up camp. They just stand in that corner, all day, flipping through manga.
It's nowhere like the anime section, which is actually pretty large and decent for such a mainstream store. I gues it's because you CANT FUCKING WATCH THE ANIME IN THE STORE.
