Amazon just started a new promotion that allows you to rent one movie for just $0.99, regardless of the regular rental cost. To get in on the deal just pick any movie out of the 49,000+ that qualify, and click the “More Purchase Options” link on the page. In the pop-up that appears, click the “Redeem a gift card or promotion code” link and enter the promo code MOVIE99. Then proceed to rent the movie and you’ll only be charged $0.99. The discounted price won’t appear on the movies listing or during checkout, but you can check you digital order history to verify that you were only charged $0.99. If you have digital credit for selecting no-rush shipping, which you can check here, the credit will automatically be used. Remember, once you rent a movie, you have 30 days to start watching it and 48 hours to finish once started.
