The discussion over in the "One too Many" thread has brought up an interesting question for me.
How do you as a player / gm / group even buy roleplaying books and supplements?
My group consists of two parts. One part me and 2 close friends whom I introduced to roleplaying and a second part of "strangers" whom I have invited or have joined my game via some sort of search for players. I can't speak for the second part but for me and my close friends we usually only buy the core rulebook of something that we want to play with maybe the advanced players guide (IH, IT etc...) at a later point in time.
As the other two members of the first part more or less got "dragged" into roleplaying by me I'm usually the one that buys the books (also the one with the most disposable income but that's a different story). The exception to this was the Book of Justice which my brother gifted to me and the Creatures Anathema which one of the other players lent me about a year ago (when he joined my group) and hasn't requested back since.
Among the three of us in the first group there only exists one copy of the DH core rulebook and the RT core rules (also only one copy of Inquisitors Handbook and Into the Storm) this keeps costs relatively low (especially compared to what I believe what some people on the forums are doing who buy everything that is out there). As I said I can't speak for the second half of the group, all I know about them is that both of them own their own copy of the Core Rulebook and I think that's about it.
Well anyway enough about me. I actually want to know how other people and groups are handling buying roleplay books and supplements.
