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

Through October 12 at Six Flags Great Adventure & Wild Safari in Jackson, NJ, purchase a 1-day adult admission ticket for $15 via coupon code "LISAGA09". (You must first select the correct park and then enter the promo code box in the top right-hand corner of the page.) That's $35 off the regular price and the best deal we've seen for these tickets in several months. Tickets must be printed out at home, which adds $5; they can't be shipped.
