Well I get some of my manga from the store and I get some manga off of mIRC like Hellsing which was finally liscensed here (el w00t).
I get a lot and I mean a LOT of my anime off of Kazaa and Bittorrent. Ask BF about how much I have.
I only purchased one anime DVD which was the first volume of Love Hina. I plan to purchase the entire Hellsing series (English dubbed) for 25 dollars off of discountanimedvd.com. I also plan to buy the Saikano series from the same place for 35 bucks too.
