I have dug around the net for a little while now, and other than direct purchase from Japan I am having trouble finding light novels. Specifically for several anime series I liked and want to read the originals for. Anyone know where I can find light novels in general for purchase or otherwise?

and a good japanese futon mattress as well.

i'm moving from a house into an apartment and am scaling my life down significantly. this seems a pretty good option... but unfortunately i don't know a whole lot about either of these (yet) so i'm looking for some guidance.

thanks!
