Nostalgia bathes everything in shades of gold, which is why many financial advisers suggest investing in discarded love letters and fondly remembered bureaus. Immerse yourself in a richer past with today’s GrouponLive deal: for $15, you get two adult tickets to Grace Kelly: From Movie Star to Princess at the TIFF Bell Lightbox (up to a $30 value). Tickets are valid from December 22, 2011 to January 22, 2012.

Grace Kelly: From Movie Star to Princess plunges fans into a carefully curated collection of artifacts from the life of the fashion icon, Oscar-winning actress, and Monegasque royal. Home videos on display provide a glimpse of royal life on the Riviera, and correspondence with friends and family illuminates Kelly's psyche like a Lite-Brite Rorschach test. Iconic outfits include a reproduction of her wedding dress—designed by MGM costumer Helen Rose—her Oscar gown, and her eponymous Hermès bag. Phones enabled to read quick-response code access a gallery-wide audio guide, fleshing out details about the exhibition with commentary from writers, historians, and designers. The show takes place at the permanent TIFF Bell Lightbox, which packs numerous theatres, galleries, studios, and restaurants into its trim belly, despite a perpetual popcorn diet.

Though the box office provides discounts for seniors, students, and children, this offer is still the best deal available.
