Hello,
Saw you are finally clearing house. Sorry, I have 0 disposable income right now so the best I could offer for anything is a trade from my post. If the goal is to create space I am afraid that will not help. If I might make one suggestion. I doubt you are going to just dump everything in a dumpster, but if you get rid of it, like a couple other posts I saw I'd suggest donating to you local library or the manga libraries at conventions. I heard Sakuracon's library got hit hard by a new regulation preventing people from "lending" their collections to expand the library selection and the managers were trying to collect donations so they could keep it open next year.
You said you weren't going to the next convention... but if a friend of yours is you might think of having him bring it or doing the local library. It was the books and DVDs at the library near my home that first exposed me to manga and anime so I plan to do the same with some of my own collection when I move out.
I hope you last few days on the trade form goes well. Best of luck to you! d-(^u^)
