Valley Fair discounts

Hey you Minneapolis people ! I'll be at Valley Fair later this week, and maybe next week too. I have a Cedar Point season pass, so I am good to go, but I'd like to bring some friends. Is there any sort of discounts available ? Purchasing tickets at the grocery store, bringing a specially marked soda can, locally offered coupons ? Please fill me in. Thank you.

By the way, I'll be @ SFGAm today (Wed 7/11). See the meeting calendar for more info.

I work at Valleyfair I think they might still do the $5.00 off discount on mountian dew & pepsi deals I'm not sure, but this may have been during the preview weekends.
