The only online DVD rental offers I know from Germany are Lovefilm.de/Amazon.de (which allows you to rent up to 6 movies per month for 19 Euros) and Amango (which has unlimited rentals, 3 DVDs at a time for about 20 Euros per month).
So, to satisfy the DC interns’ need for movies, I signed up for a Blockbuster subscription today. That costs about $19 a month (incl. tax) and I will have three movies checked out at a time. The next Blockbuster store is only a few blocks away, so I can always return them in the store and get a free “regular” rental for each DVD I bring in. Nice 😉
Hope I can manage to cross some movies off the “1001 Movies You Must See Before You Die” list.
