I know what you mean...I havent paid for redbox in over a year.
Blockbuster express often has codes listed online as well.
It helps me see movies I wouldnt waste a $1 on before they hit my free HBO.
Over half the rentals arent worth $1 anyway, other than the handfull of movies worth seeing on the bigscreen, Hollywood's quality standards are really low...whats with all the lame remakes?...no new ideas out there?
