Eventually I wanna have everything, so I do occasionally buy merchandise on YAJ or something, but like... I don't have anywhere near enough money to do that, lol. So one day I'll get that stuff, but for right now I'm working on getting her complete CD discography. Price is the biggest driving factor for me at the moment, because I'm broke. So most of the Ayu CDs I get right now are used. I'm also prioritizing my favorite CDs at the moment. The CDs where, if all my mp3s died tomorrow, I'd be glad I at least had these.
Collectability is not a factor for me right now.
When buying magazines & clippings & books, I like getting stuff not many ayu fans have. That way, when my japanese gets good, I can translate interviews or books one day. Or I can scan photos from magazines that most galleries don't seem to have. I like the idea of contributing. (this is why I bought the dome tour 2001 tourbook - to scan it

I sold it not long afterwards.)
I haven't been able to get anything on YAJ in awhile though. But i'm going to LA this summer, and you can bet I'll be camping at book-off.
