Kings Dominion Discounts?

Calling all DC locals for help -- I'm visiting the DC area and am planning on taking a friend to KD for the day on Monday. I've looked around online, and the only discount I can find is the slight discount for ordering early off the KD website. Does anyone know if supermarket / movie rental / fast food chains offer any kind of discount coupons? Thanks in advance!

Found this on another website board. This is for the corporate code section of the KD website.

For the corporate code, enter VAFUN for $35.95 tickets for adults and $24.95 for children and seniors good any day the park is open.

Use code JDRFDAYS for $26.00 tickets for adults and $19.95 for children/seniors valid for the following days:
June 9, 10, 16, 17, 22, 23, 24, 28, 29, 30, and July 1-4, 2007. $2 of each ticket sold using the JDRF code goes to the Juvenile Diabetes Research Foundation.

Giant Food stores--which are located all over the D.C./Baltimore area --has discount coupons as well.
