FILLaSEAt: tickets for events

Is anyone a member of fillaseat? I found the site on groupons and I was intrigued by it. It seems to be where you can get free tickets for different events. There is a membership fee of 89.00 for a year. At the moment a discount on groupon for 45.00 for a year to different events. The membership is for two tickets when you pick up tickets for events. Thanks for the feed back.
