Six Flags: Adult 1-day admission ticket + $5 printing fee

Until 6 pm ET today at Six Flags, purchase a 1-day adult admission ticket for $15. That's more than $30 off at several parks and the best deal we've seen for these tickets in over a month. Tickets must be printed out at home, which adds $5; they can't be shipped. Limit four tickets per purchase. Tickets are valid on any regular operating day through August 16.
