And don't forget about Blockbuster, provided your local outlet hasn't already closed its doors for good. Perhaps it's an act of desperation, but the discs there are dirt cheap.

Recently I rented a DVD of Curb Your Enthusiasm--specifically, the first six episodes of the 6th season--for 50 cents at Blockbuster. You won't find Curb on Netflix streaming.

Eventually, of course, DVDs will go away entirely. Some critics have suggested that Netflix, by separating its disc and streaming services, is really hoping to by making it unattractive to consumers.

I'm not sure if that's true. But for this Netflix subscriber, the DVD service no longer makes sense.
