It all comes down to the location and target group of who you want entering your video rental shop.  Here in Canada where I reside, there are quite a lot of places that offer mainly indie and foreign films to the discerning public and people who appreciate a great film that isn't typically hollywood.  This one video stores aside from offering your usual membership, can also e-mail it's users up-coming films, gives it's new members a catalogue of all it's movies in stock.  They also have a great website which one can purchase movies from and have a wide range of categories to choose from.
