When you rent movies online you have such a wide choice that you need an easy way to search, and an online DVD store can use the power of online local search engines to make it easy for you. Each site has its own search engine that will provide you with a list of movies that conform to any search criteria you use: whether by actor or actress, genre, the movie title or even one or two words within the title, then you will be provided with a list of movies that the online movie rental company has to offer.
Fast Turn-Round
You want a fast turn-round by post. Whereas an offline video store will immediately exchange your video for a new one, a postal service cannot do that. What you should look for when you rent movies link to website online is:
a) First class post both to you and back to them. Postage should be free to you so you don't have to worry about buying the right stamp for the weight of your DVD, and the envelope should be self-addressed. A Freepost self-addressed envelope is what you should be looking for.
