deal on Living Planet Aquarium

So if you read my post about the Living Planet Aquarium you'll know how much we love going there.  Today Citydeals has a great deal of 50% off annual membership for one adult and one child.  This makes it $21 for these annual memberships.  If you use the coupon code TXT15 you'll get an additional 15% off so that even with shipping/handling you can get the two memberships for under $19!  Of course you only get one adult and one child membership and there's a limit of one purchase per household, but it's a great deal!  Here's the link for the deal http://www.citydeals.com/?ref=CDUMTQzODIz
