How to score free, wireless Xbox 360 controllers

It's simple really, you had to have recently just bought your Xbox 360. Recently enough so that you can return it. See, the trick is, return your Xbox 360, without the controllers, to the store your purchased it from and tell them it's not reading the games or Dvds for some reason. Just tell them you want to exchange it and they'll let you go grab another one. Some people may actually open the box to make sure everything's there, most employees don't care though so. Being that Xbox 360 controllers cost so damn much, this should provide some relief. Is it a bit scandalous? A bit. Do this at your own descretion and don't sue me...because it's just an Xbox 360 controller, sheesh.
