Where can I get out-of-print (OOP) Greyhawk materials?
As a large portion of the Greyhawk products are OOP, this is a good question. Currently, eBay is a great source, but you may pay a premium for popular items (like the T1-4 or WGR4). Another source is online games dealers like Titan Games (www.titan-games.com), The Dragon’s Trove (www.dragontrove.com), or Noble Knight Games (www.nobleknight.com). For those of you dinosaurs (like the FAQ author) who remember Usenet, the newsgroup rec.games.frp.marketplace is a good place to look. Finally, Wizards of the Coast has been scanning older products and selling them online as PDf files for $4-6 each. They are finally (at the time of this writing) getting to the Greyhawk material (store.wizards.com).
