NetFlix Unlimited Streaming at 1 DVD Account Level

I didn't realize that you can get unlimited NetFlix streaming at their 1 DVD $8.99/mo account level. Now that I am using a Roku player with an HDTV, that seems like a great deal for all the content they offer. 

Netflix costs $8.99 a month. You get 1 DVD out at-a-time which you can exchange as often as you want. Plus, you can instantly watch online on your PC or Mac or right on your TV via an Internet connected Netflix ready device. Instantly watch as often as you want, anytime you want.
