For cards, there are a couple of mail-order houses that advertise on
rec.games.trading-cards.marketplace but you pretty much have to trade.
If you have access to the WWWeb, SJGames has pointers to several
locations that have a complete set of the rules online. Try the
Illuminati:NWO home page: http://www.io.com/sjgames/inwo/
This page should lead you whereever they want you to go.
Call GAMESCAPE in Palo Alto Ca, they have at LEAST 200 boxes of booster
and probably around 30 boxes of starters left. They are probably the
biggest on the west coast.
Their number is: (408) 322-GAMES
