It's one voucher per person and expires September 9, 2011. It has to be used on Fandango.com (you can't take it to the movie theater), and each ticket price can't exceed $15. I don't think there are any other restrictions! I'm buying one under my card and one under Ryan's... he loves going to the movies, so I was pretty thrilled to see this one. Here's a link in case you want to get in on all the movie fun!
Note: The links above are referral links and if 3 people click and buy from those links, my movie tickets are free. If you're going to buy.... please use my link? Pretty please???
