Dragoncon 2009 opens September 4th, so I though this a good time to link to my helpful list of Dragoncon vendor websites at RPGSeek.com. The directory includes a vendor site description as well as the link, so you have an idea what they are selling before you actually visit the site. A surprising number of gaming vendors are attending this year. so it is worth a look even if you are not interested in the media portion of the event.
I also have the vendor and exhibitor list up for Gen Con 2009 for those seeking some post-convention shopping.
