Living Social: Living Planet Aquarium - Annual Pass for Adult & Child $18

Living Social has a great deal on an annual membership to the Living Planet Aquarium. Get an annual membership for one adult and one child for only $18 (that's $9 per annual pass). Not sure how long these will last.

A regular day pass is $9 for an adult and $7 for a child, so this is a great deal to get an entire year pass for $9 each.
