If you're one of those trendy new staycationers (don't you love how the marketers find a way to make not getting an exotic vacation sound cool?), then you'll want to know that Six Flags Great America has a twofer deal going on. It's only available online and only good for visits through July 3.
The deal means it costs just $27.50 a person to get into the area's biggest amusement/water park. After July 3, prices go to $39.99. It's still a savings off the standard $54.99, but why pay more than you have to? Buy the tickets now.
