If you're planning to buy-and-try, the best place to do so is probably
Fictionwise, where you can take the price down considerably with a good coupon.
Also, obligatory linkage to the "
Houseplants of Gor" parody, which according to people who've actually read the books is a fairly good representation of them.
Fun fact: There's an
entire subculture devoted to recreating the Gorean principles for role-play/real-life relationships (link mostly safe-for-work as long as you don't auto-load videos, from an article posted to Norman's e-publisher's blog), which I am told is looked down upon by mainstream BDSM practitioners because of its lack of safe words.
