$2.00 per day is not too bad for the convenience. Blockbuster charges $9.00 for 5 days which is almost $2.00 a day. The bad part about Blockbuster is say you rent the game, then get home and find out you dont like that game. Pow $9.00 down the drain for 1 day. With the red box you would only use $2.00.
So far Family video is the cheapest way to rent games in my area especially if I get half off for the month. With the half off I can rent from Family for about $0.75 a day. It really doesnt get much more convenient than this.
But if the game you want is not in, then the Red box really is not bad at all for only $2.00 a day. This is going to be very successful.
