Yeah, the group buy sounds like a decent idea. Especially considering Bardoly, ElSeven and I (the first three people to comment on this) are all local to one another.
Yeah, it would probably save on shipping if one of us here in the Chicago area were to order a bulk lot of 10-20 (however many people want), then just mail them out from here. The difference in international versus domestic shipping should save us some $. I would be willing to either give $ up-front to someone willing to do so (I nominate you, Dragonmaster Dan. :-" ), or to be the one to do the ordering if this were something which people would like to do.
