The basic membership is 3 DVDs at any one time for US$21.99 (just went up $2 recently). But you can switch to a 6 DVD subscription as well. But I'm not sure what the price is. I now have Master & Commander and Kill Bill vol 1 coming to me in the mail (sent today). You can send them back in any order or spread them out. So if you want to pay the cheap rate, get 3 discs from a 6 disc set now, watch 1 and send it back, then watch the second while waiting for your next disc, etc. See where I'm going? It can be done. I've got the Futurama sets in my queue along with Band of Brothers and Gilmore Girls for my wife.
