I just logged onto Chase Bank to look at my credit card statement. The ad states that Chase cardholders can buy a 4-pack of 4 tickets for $99 to select Six Flags Theme parks. The offer ends June 30th. Offer is valid only thru sixflags.com. The parks are:
Discovery Kingdom, Magic Mountain, Elitch Gardens, Over Georgia, Great America, Kentucky Kingdom, America, New England, Great Adventure, St. Louis, Darien Lake, Fiesta Texas, and Over Texas.
