I'm looking to sell my 3.5 books as well and saw this thread, so I thought I might as well use this, instead of creating a new thread. Hope that's ok.
First lot (sorry for the bad image quality, I can take a new shot if that's needed). Dungeon Master's Guide, Player's Handbook, Monster Manual, Monster Manual 2, Manual of The Planes, Rules Compendium, Psionics Handbook, Complete Warrior, Complete Psionic, Tome And Blood, Song And Silence, Sword And Fist.
Second is another Monster Manual
Last is another Tome And Blood
As to the shipping I live in Denmark.
I haven't created any listings on ebay yet, since I'm unsure if that's the way to go, so any advice on selling these old books are much appreciated.
