When ignored for a long time, sports memorabilia becomes angry and purposefully decreases its value by getting plastic surgery to appear younger. Cherish rebellious relics with today's Groupon: for $12, you get two admission tickets to Canada's Sports Hall of Fame in Canada Olympic Park (a $24 value).

With 11 sport-infused galleries, Canada's Sports Hall of Fame preserves and celebrates the nation's exceptional athletic feats with artifacts and interactive experiences honouring more than 500 stars from 60 different games. After its grand opening in a brand-new facility on July 1, visitors holding admission tickets (a $12 value/person) can catch a 10-minute introductory movie in the hall's new 120-seat theatre, then careen through the galleries while surveying photo archives, a film library, and notable relics such as trophies and signed memorabilia. Rocket Richard's hockey jersey hangs for adoring eyes to spy, Clara Hughes's bike from the 1996 Olympic Games patiently waits to chase glory once again, and Terry Fox's running shoes have been carefully dipped in chocolate so that all guests can have a nibble. Interactive exhibits grant fans the chance to shadowbox with legendary heavyweight Lennox Lewis or race world-record holder Chantal Petitclerc in a wheelchair.
