My HP collection as of 14 April 2011. It's missing one (Gringott's Coin Collection Book) because I couldn't find it then. I found it a few hours later sitting among the other coin collection cans in a corner. 8I
EDIT: Oh my goodness! I totally forgot about my HP LEGO sets. Hahahaha. WELL. Probably when my other stuff arrive, I'm most likely going to update this. Maybe sooner, we'll see.
