You seem to be missing the point of Netflix streaming vs. Amazon. Netflix is all you can eat so I can watch as many movies as I want for a flat fee whereas Amazon charges per movie just like you'd get your local blockbuster or redbox.
Sure and the all you can eat buffet is a better bargin as long as you like what they are serving.
If gave you a choice of 2 meals A) you're favorite dish( no 2nd's ) $12 B) a buffet for varius kind of animal feces for $1 and it's all yu can eat. Which are you going to take?
Amazon may be the same price as Blockbuster or redbox, but I don't have to get out and I don't have to return the movie. By the way every now and then Amzon has discounted rentals.
here's crapload for $2.99. I'm renting Star Trek TONIGHT. They even have a few for 99 cents.
