I just discovered Book Depository has a US version of their site (been buying from their UK site for a while now). Out of curiosity I did a search on some RPGs and noticed that they have them there for sale.
While I try & support my Local Stores in Melbourne, It's hard to pass up the savings from buying from here. Plus Book Depository delivers free to a lot of countries (including Australia)
From some searching the appear to stock Chaosium (Call of Cthulhu etc), Catalyst Games (Shadowrun etc), White Wolf (World of Darkness), Wizards of the Coast (D&D etc) amongst others. Was disappointed they don't appear to stock Pinnacle stuff (Savage Worlds)
Free shipping worldwide on all books from The Book Depository
Does anyone know of other online stores that stock RPGs at reasonable prices?
