On two or three occasions I have bought stuff from Digital City in Sydney. Each time they did the usual "you need to give us your address for warranty purposes" bullshit. So yesterday I received three identical mail-outs from said organisation via Australia Post, who were forwarding stuff to me from my old apartment.

How did they manage to send me the same flyer three times on the same day? Well, how about by getting every single instance of my (previous) address wrong in a slightly different way?
