I don't need it so quick that I would resort to a used book store, especially since I would prefer them going to someone who is going to actually use them (Where I am in south Louisiana the used book store would be the kiss of death for many of my books). The price has me unsure since I am not positive and what might be rarer, but as for the list:
Unearthed Arcana
Book of Exalted Deeds
Book of Vile Darkness
Manual of the Planes
Planar Handbook
Psionics Handbook (3.0)
Savage Species
Complete Warrior
Complete Divine
Oriental Adventures
Arms and Equipment
Heroes of Battle
Eberron
Magic of Eberron
Races of Eberron
Five Nations
Sharn City of Towers
Revenloft Campaign Setting
Ravenloft: Denizens of Darkness
Ravenloft Dungeon Masters Guide
Van Richten's Arsenal I
Van Richten's Guide to the Walking Dead
Ran Richten's Gazateer (II, III, and IV
Heroes of Light
Secrets of the Dread Realms
the only things I am truly hesitant to get rid of are the Ravenloft Campaign setting and the Eberron books for Sharn and the Five Nations.
