Do you buy any manga books  

I usually have to buy manga since there is no anime on television here.
So far I own quite a few manga books, but I've only complete Death Note. I have D.Gray-Man, Fruits Basket, Model, Cresent Moon, Knights of the Zodiac and Vassalord.

Although series some won't get finished (ie: Fruits Basket, Cresent Moon, and Knights of the Zodiac) because they're way too much money, I don't like how the series goes/ends, and they're hard to get ahold of because my local bookstore doesn't carry them.

I bought some naruto manga whilst i was visiting the UK and thouroughly enjoyed it, however it is to expensive to purchase large amounts

well, I do buy manga in the past, like dragon ball, doraemon, samurai deeper kyo, shaman king, magister negi magi, yu-gi-oh!, one piece, and many more. . . all of them are quite complete in the series. . .
but new recently, I rather read online, -_-, except there a single series manga that only one book it ends and a compiled series of manga in 1 book like a thick manga, in my country it's like shonen magz, shonen star and so on, LoL
hey, it's a good feeling when the manga is in a solid shape rather in data, so why not buying manga? LoL

I usually dont purchase books period. I just dont go to bookstores, read a few books and choose which ones look good. I usualy purchase my mangas while I am attending a convention.

I've drastically cut back on my manga hoarding. Last time I counted, I had over 500 volumes of manga. I used to buy at least four or five volumes a month but I'm just too strapped for cash to do that now. Plus, some of those series, especially the Shounen Jump ones, are way too long. I don't really want to try and catch up on those, it's too spendy. I'd be lucky if I even get one volume a month these days. A lot of these new series coming out doesn't interest me enough to make me buy the manga.

I read a little bit of manga. Although, at this point, I haven't read one in a while. The types of manga I like to read are comedic ones. (If I don't read something funny, I tend to fell sleepy after reading just a little bit.) And, no, I don't buy any manga books. I just read them online. The reading process is a little slower since each page has to be loaded, but at least it's free. I mean, if you want the whole series on a particular anime, it's going to get quite pricey if you buy them all.

I buy Legend of Basara mangas on occasion, when I can find them for a couple bucks. I just like the story, and the anime for it was cancelled back in the day...so this is the only way I can have the story in its entirety.
