I'd say $2040 on dvds, not including the ones that were stollen a year back (just counting what I have now), about $750 on tapes which I don't use for anything (I might get $200 if I pawned them at $5 each, that's it, but I'd probably be lucky to get $50 for the entire mess), about $300 on manga ($150 of which went for Earthian alone - for 5 used books that I can't translate >.< ), and around $200 on wallscrolls. So around $3340.
Not too bad in 4yrs, I can just imagine if I'd known about anime sooner. ^_^; I could buy a cheap car for that much money.
