GOG has a D&D-themed sale and it's pretty hot - buy one, get one free - plus Temple of Elemental Evil free one top if you don't already have it:
Surprise sale for all of you RPG lovers! From now until 23.59 pm EST on the 28th of February, we’re offering you a chance to buy one D&D game and get one FREE! More than that, though, if you buy ANY D&D game during our sale, you will get Temple of Elemental Evil for free if you don’t already own it!
Thanks jhwisner! Think I'll buy PS:T and grab BG2 and ToEE for free just so I don't have to dig out disks when I replay.
