Yes, I have lots of AC stuff, but nothing too rare except for the signed large maps - which are not cheap. Only 100 of these were made and I have... a bunch.
I also should have most if not all promos, some shirts and other trinkets.
I do have an AC IV PK and an AC 1 PC review disc, but they are only offered to people I already know since they are traceable (even more than the maps). :-)
