Over the past month, in an audacious reversal of cultural norms, Topshop's target market has made the market its target. The shop has become the focus of activist group, UK Uncut, which has staged a series of high profile sit-ins at stores around the country. Last weekend, the biggest shopping Saturday of the year, Topshop's flagship store in Oxford Circus was closed for the third time by a flashmob of "citizen volunteers" who had mobilised via networks developed on Facebook and Twitter.
