You don't have to wait in line or leave your home to rent DVD movies online. You can take as much time as you want browsing online databases for movies and films of interest. You can do everything from the privacy of your home or from anywhere as long as you have access to a computer and an internet connection. After you've selected the movies that you want to rent, you just click a button and the valet reviews are sent to your home for you to view and enjoy. After you're done with them, you simply return them to the movie rental service via a prepaid mailer.
Compared to renting from a shop offline, online DVD movie rentals are far much cheaper. You'll get better prices and you can easily compare different services using an online shopping comparison search engine. This can save you money as well as help you get a service that best suits your needs. Some rental shops have online versions where they offer web only prices. You would have to sign up from their website in order to benefit from the cheaper prices being offered.
Another advantage is convenience. With internet rentals, you don't need to go out to the store to get your favorite movies. Just logon to their site and browse and select titles online from the comfort of your own home or from anywhere. The movies you select are posted to you for free and you can return them by post for free too.
