Planning on going somewhere with Frontier Airlines? Groupon has a $50 credit for $25

There is another Groupon deal that has a $50 Frontier Airline credit that you can get for $25.  You have to book your flight by 11/15/11 and fly by 2/27/12.  You can purchase more than one credit but can only use one credit per flight booked, and only valid for new bookings. Link
