Amazon has a cool new feature allowing you to buy select DVD or Blu-ray titles, and watch instantly with an Amazon Video On Demand feature called Disc+ on demand. This allows instant gratification, lets you save a trip to the video store and then the proper DVD arrives in the mail a few days later. Of course once YOU have seen the movie, you might want to give the DVD away as a Christmas… like re-gifting only not so cheeky.
