Bodies of water are frequent metaphors in poetry, due to their unfathomable depths, unknowable sprawl, and unattainable porpoises. Plumb the enigma of the ocean with today's Groupon: for $119, you get a Salish Sea Advocate family membership (a $250 value) to the Shaw Ocean Discovery Centre, located in Sidney.

The Shaw Ocean Discovery Centre is dedicated to exposing aquanauts of all ages to the marvels of the sea. The Gallery of the Salish Sea re-creates local habitats, structured with air bubbles so visitors can enjoy a panorama of the wolf eels, rock fish, and octopuses that populate the coast. Touch pools provide the opportunity to shake hands with a sea star, tickle an urchin, or arm-wrestle a kraken, and the Ocean's Heartbeat exhibit allows visitors an up-close look at the tiniest denizens of the deep through the lens of a microscope.

A Salish Sea Advocate family membership entitles two adults and their children or grandchildren ages 3–17 to a full year of unlimited, free admission both to the aquarium and educational Floating Ideas lectures, as well as access via secret handshake to special members-only hours once a month. Members also get a 15 per cent discount on all merchandise, programs, and special events and regularly receive the centre's e-newsletter. Show off your aqua affiliation to envious highwaymen with a complimentary Shaw Ocean Discovery Centre member decal and a sea-star lapel pin, or treat four friends to guest passes.
