Anime
I'll advise you to not buy (most) Anime (movies excluded) from the mall or even Amazon because it's expensive. All the Anime I have I've gotten from China or Japan off of EBay. It's usually only subtitled but that's okay cause I'd rather it be subtitled anyways.
Manga
It doesn't really matter where you get Manga beacuse it all tends to be the same price. Del-Ray Mangas are a few dollars cheaper off of Amazon.com and if you spend more than
25$ (three books) you get free shipping. I always buy Del-Rey off of Amazon cause the three books from their will save like 6-9$. Some mangas you can only find on Amazon though.
Remember that β's means it's hard to find.
Series' I'm currently reading...
How to Draw Manga Drawing Books
These are drawing books I desire. I'll advise you not to stray from the list because I don't wish to collect every book and I've looked through many of them (you can find them at MediaPlay). At the bottom are the books I have (with the - minus signs in front of them). DON'T get those.
Music
Oh yay! I don't know where to get these. I think Suncoast has them. =)
