The title of this thread sucks. You can't call something free and then turn around and charge for it. And don't say it was free for you either, you had to buy a Big Mac or whatever to get it. False advertising is bad.
Its a code from a peel off contest for a free Redbox rental for one night. That's what it is. That is not false advertising, you just need to find a job as a grammar school teacher or a newspaper editor or something and maybe your time spent nitpicking everything would be more meaningful.
