Go to fandango.com and click on the showtimes tab.
Once in the showtimes tab, right below your first local theater listing there should be a highlighted banner saying "Want to get a free Fandango ticket?" Click on it. (If it does not show up, click on The Fandango Ticketing Theaters tab, it should show up there)
click on the banner and a popup will appear. On the offer page, Look for the HULU Plus offer.
When you click on the Hulu+ offer, it will take you to a screen to put your information in. Put all the required info, on the next screen choose the 1 week Free trial! Put in your credit card information (you will NOT be charged.)
Doing it this way you get the $12 Free Fandango ticket without any expense out of your pocket.
**IMPORTANT** DO NOT forget to cancel your subscription before the week ends of you WILL be charged for a month subscription!
**NOTE*** The code for the free tickets expires in 60 Days from registration for them!!
P.S I searched and this wans't coming up on the threads but I hope this isn't a repost. Happy Hunting
UPDATE:some people are able to do it multiple times using incognito browser with different emails, names, and credit cards but you need to create a new fandango account each time but worth it for free tickets!
+++NOTE+++ As of 5/19/2013 This deal is still LIVE!
