The Convenience Fee charge to purchase Tickets through Fandango is $1.50 per ticket purchased online.
So if your movie ticket is say $11.50 that you're purchasing online then the total cost for the movie ticket including Fandango's convenience fee would be $13.00
Fandango does not make any money off the movie ticket itself so they have to charge a convenience fee to make money and I find that the Fandango's Convenience fee is well worth it instead of standing inline for tickets.
