Baltimoreans can strengthen their supplies of geek chic by 10+ health points with a cornucopia of sci-fi and fantasy television and movie memorabilia. The one-stop fan shop caters to devotees of Doctor Who, Magic: The Gathering, Star Trek, Star Wars, and Star Blazers, but is unfortunately fresh out of Star Jones action figures. Double your fulfillment of fantasy by combining the cosmic power of two Groupons to cover one hefty purchase of equal parts Marvel and DC, or buy multiple Groupons for all of your Comic-Con confidants.
