the chart is wrong, you can't watch 30 movies using netflix and 1 movie out at a time. At most it would be 15, more than likely at most 10. So it barely wins.
Redbox also has Blu-rays for $1.50.
The thing against Redbox is the movie studios, half the movies don't come out on Redbox for over a month.
Also with Hastings and Family Video lowering prices to around Redbox prices, i see myself going less and less to Redbox. ($3 for blu-ray, return next day get $1.50 credit for next movie - Hastings).
