I used to buy manga and spend hundreds of dollars on it, but I stopped buying it when I found out that I could read manga free from online.
Still, I do buy manga I really like such as Shugo Chara and ARIA.
As for anime, I use to spend thousands of dollars on DVD but stopped buying it when I found out that I could use YouTube to watch most of the anime I want for free.
Still, like the manga, I do buy anime I really like and I occasionally buy blu-ray copies of anime too so I can watch it on my HDTV! ☆(≧ω≦)
