Exclusive video: Personal shopping with Marcus Coates

Located among the designer togs on the third floor of Selfridges, Miranda July’s multifaith charity shop has been a huge hit with art-worlders and the general public alike. Not only does this Artangel project-cum-retail outlet benefit four different religious charities, its price points are the same as charity shops nationwide. During Frieze week, July extended a personal shopping service to a select group of fellow artists: Seth Price, Marcus Coates, Georgina Starr and Cornelia Parker. Her films of their encounters—which often seem to have as much to do with therapy as with retail—can be viewed exclusively here.
