I like the layout of their website and it is very easy to use. Picking up the tickets at the theater is very easy, too. Just slide your card (Debit or Credit) in the machine and out pop the tickets. No waiting in long, snake lines.
I wrote a list of movies from the previews that I want to see in the future. You can be sure I will use Fandango to purchase the tickets when the time comes. After all, Harry Potter and the Deathly Hallows Part 1 comes out in November 2010 and Part 2 comes out in July 2011, both well before the Ancient Mayan Doomsday and End of Times in 2012.
(This was not a paid post - yet. This was a test. But I really do use Fandango.)
It's not easy to comment there, so you can come back here to comment if you want.
