ISO Baltimore Aquarium Coupon/Discount

My parents will be visiting from out of the country in October/November and I thought we could go to the Aquarium. Anybody know of any discount sites that offers discounts/coupons for admission? Thanks.

I'm not sure how far away you live, but when I used to live there for school (5+yrs ago), they had $5/person admission after 5pm on Fridays.
