Digital Rentals allow you to rent videos for 24 hours (or in some cases, 5-day rentals are available). When you rent a video, an account will be created and a link to access the account will be emailed to you. Your account will contain a list of all the rentals that you have purchased. To watch a video, simply select it from the list and click play. Your rental will not begin until you activate the video, so feel free to buy in advance!
You can also "gift" rentals to your friends! (Gifting is easy, once you have purchased the rental, you will find an option to "gift it" when you log in to your account.)
