ticket price for Indycars and ALMS

[mdosu]

The Baltimore race is this weekend.

Question: Generally, are tickets at the gate more expensive than the ticketmaster online prices?

I know this may be dependent on the track or series, but ticketmaster was contracted out to do ticketing for this event.

Livingsocial ran a deal for tickets and paddock passes, but they didn't include it for the practice session on Friday.
