M&M's Day at Six Flags. You'll need to like the page to get the special code to save $25, which you can use to save off up to two general admission tickets on 9/3/2011 only. You will use the code to purchase tickets online only; you can't use the discount at the ticket booth at a Six Flags.
Fine print: The ticket(s) will be good at any Six Flags within the continental US, except for The Great Escape. It's also not valid for water parks, Six Flags Wild Safari, Six Flags Mexico, La Ronde, or 3-Park combo tickets. Limit 1 code per Facebook user/person.
If you decide to go, have lots of fun! Summer's fading and this could be that one last fun family activity that you can do before school starts.
