I'm sitting at the computer with the Topshop website up on the screen and cannot pry my eyes away from the GPS screen for the Topshop Heartschallenger bus. As a promotional move for the New York Topshop store which they swear is finally opening in April, a bus is driving around New York giving out gift bags and free gift cards for an undisclosed amount. I wouldn't care so much but Topshop is generally fabulous so if the bus comes within a few blocks, I. am. so. out.
