Weekly Cinema. I have been using it for two months now, and thought it was worth mentioning to all of you. For signing up you will receive a FREE movie ticket (it's a Fandango ticket code, so you'll want to check if your theater accepts Fandango tickets).
You will be asked to enter your credit card info but after that you can log into your account and at the top click the Cancel Me link, even if you cancel you still get your to keep your FREE ticket! You will be charged for $19.99 for 4 tickets within 3 days if you don't cancel. BUT that is a HUGE savings for our family since we pay $10.50 for adults and $8.50 for kids. And for every friend you refer you will receive a FREE ticket.
It is really easy to SIGN UP, and just as easy to cancel.
