As everyone knows by now, sprawling indie boutique Shotwell is moving from Union Square to the Mission and is closing up shop any day now. To celebrate the ch-ch-ch-changes, the boutique is inviting all of its friends and faithful shoppers tonight for one last hurrah. In addition to live beats, free drinks, and celebratory dancing, the "Last Call" party will also feature extreme discounts (including 30% off Comme des Garcons Play!) on all the goods left in the store.
